This is all covered in the which I will aim to summarise here. ESXi uses storage APIs known as the Pluggable Storage Architecture (PSA) to manage storage multipathing. Useful terms to understand in relation to PSA include: • PSA – Pluggable Storage Architecture • NMP – Native Multipathing Plugin • PSP – Path Selection Plugin – Handles path selection • SATP – Storage Array Type Plugin – Handles path failover for a storage array The default NMP plugin provided by VMware has 2 sub-plugins – SATPs and PSPs. These are also provided by VMware, although there are also third party ones available. In addition, a third party may also make their own multipathing plugin available, which can replace VMware’s NMP. EMC PowerPath is an example of this. EMC PowerPath for Solaris Installation and Administration Guide 9 Preface Where to get help EMC support, product, and licensing information can be obtained as follows. How to install emc powerpath on solaris 11 enable ssh However, if you have SSH on installation time, ignore or have started the installation with a minimum. 5.To install PowerPath from a downloaded tar file, for example, after downloading the package from Powerlink, use this procedure: 1. Select or create a directory where you can unload the PowerPath tar file. For example, type: mkdir /unload 2. Change directories to the unload directory. Note: Ensure that the unload directory is empty. Installing a PSA Plugin As stated above, PowerPath is an example of a PSA plugin you may want to install. It’s recommended that you put the host into maintenance mode before installing the plugin. After downloading the PowerPath/VE trial, extract the contents of the zip file. You can download the software. Once you have extracted the files, copy the locate the VMware zip file and secure copy the files to the host. You could also upload the files to a vMA or to another server with vCLI installed. Place host in maintenance mode or move the VMs to another ESXi host then perform the installation by running: esxcli -s ESXiHostAddress software vib install -d /PathtoExtractedZipFileContents/index.xml: /vmfs/volumes/4f27b82e-3fc1540e-bf6b-000c295da2d9/EMCPower.VMWARE.5.8.b342 # esxcli software vib install -d /vmfs/volumes/datastore1/EMCPower.VMWARE.5.8.b342/index.xml Installation Result Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.

If your server has two HBA cards connected to EMC SAN storage device, you can implement load-balancing, and fail-over on the HBA cards using the EMC PowerPath software. Powermt management utility helps you manage I/O paths from the server to the EMC storage device. In this article, let us discuss how to use powermt command with practical examples. Powermt display – Display High Level HBA I/O Paths powermt display command (without any arguments), displays the available HBAs and their current status. The following examples, shows that there are 2 HBAs connected to the server, both the HBAs are in active condition with 2 I/O path’s each. Qla2xxx indicates that it is using the Q-Logic HBA card. This also indicates that the connected EMC device is CLARiiON, as it displays a value for “CLARiiON logical device count” as 1. # powermt display Symmetrix logical device count=0 CLARiiON logical device count=1 Hitachi logical device count=0 Invista logical device count=0 HP xp logical device count=0 Ess logical device count=0 HP HSx logical device count=0 ============================================================================== ----- Host Bus Adapters --------- ------ I/O Paths ----- ------ Stats ------ ### HW Path Summary Total Dead IO/Sec Q-IOs Errors ============================================================================== 1 qla2xxx optimal 2 0 - 0 0 2 qla2xxx optimal 2 0 - 0 0 2. Powermt display dev=all – Display All Attached LUNs This is the most frequently used powermt command, which will display all the attached logical devices to the server. # powermt display dev=all Pseudo name=emcpowera CLARiiON ID=AAA0 [dev-server] Logical device ID=111111111 [LUN 1] state=alive; policy=CLAROpt; priority=0; queued-IOs=0 Owner: default=SP B, current=SP B Array failover mode: 1 ============================================================================== ---------------- Host --------------- - Stor - -- I/O Path - -- Stats --- ### HW Path I/O Paths Interf. The above command output indicates the following: • Pseudo name=emcpowera – The device name that can be used by the server. For example, /dev/emcpowera. • CLARiiON ID=AAA0 [dev-server] – EMC CLARiiON CX3 serial number and the server name. • Logical device ID=11111111 [LUN 1] – LUN number. For example, LUN 1. • state=alive; policy=CLAROpt; – This displays that this particular LUN is valid and using the CLAROpt policy. • Owner: default=SP B, current=SP B – This indicates that the default (and current) owner for this LUN is storage processor SP B. Powermt display dev=emcpowera – Display specific LUN When there are multiple LUNs connected to a server, you might want to view information about a specific LUN by providing the logical name of the LUN as shown below. # powermt display dev=emcpowera Pseudo name=emcpowera CLARiiON ID=AAA0 [dev-server] Logical device ID=111111111 [LUN 1] state=alive; policy=CLAROpt; priority=0; queued-IOs=0 Owner: default=SP B, current=SP B Array failover mode: 1 ============================================================================== ---------------- Host --------------- - Stor - -- I/O Path - -- Stats --- ### HW Path I/O Paths Interf.

Powermt check_registration – Display PowerPath Registration Key / Status If you’ve lost the PowerPath registration key that you’ve used during the, you can retrieve it using the following command. # powermt check_registration Key AAAA-BBBB-CCCC-DDDD-EEEE-FFFF Product: PowerPath Capabilities: All 5. Powermt display options – Display EMC PowerPath Options Displays the high level EMC SAN array options as shown below. # powermt display options Default storage system class: all Show CLARiiON LUN names: true Path Latency Monitor: Off Path Latency Threshold: 0 Sec. Storage System Class Attributes ------------ ---------- Symmetrix periodic autorestore = on status = managed CLARiiON periodic autorestore = on status = managed Hitachi periodic autorestore = on status = managed Invista periodic autorestore = on status = managed HP xp periodic autorestore = on status = managed Ess periodic autorestore = on status = managed HP HSx periodic autorestore = on status = managed 6. Powermt display hba_mode – Display PowerPath HBA Mode This is similar to #1, but displays whether hba is enabled or not, as shown in the last column of the output. # powermt display hba_mode Symmetrix logical device count=0 CLARiiON logical device count=1 Hitachi logical device count=0 Invista logical device count=0 HP xp logical device count=0 Ess logical device count=0 HP HSx logical device count=0 ============================================================================== ----- Host Bus Adapters --------- ------ I/O Paths ----- Stats ### HW Path Summary Total Dead Q-IOs Mode ============================================================================== 1 qla2xxx optimal 2 0 0 Enabled 2 qla2xxx optimal 2 0 0 Enabled 7. Powermt display path – Display available I/O Paths. This displays all available path for your SAN device. Awesome list. I love powerpath. I had to debug an issue with little to no help from the customer (they owned everything outside of the server) and would not let me see anything on the switch. I knew there was a bad cable but they made me prove it and EMC powerpath was definitely helpful. One command to add for AIX users. AIX we are familiar with “cfgmgr”. There is also an “EMC” special version of the command as well emc_cfgmgr (shell script) Basically (with help from EMC) part of the recovery process was to rebuild the paths once recovered powermt check (or powermt check force if you have to ) powermt config powermt save emc_cfgmgr powermt display dev=all.

After I did the last round of software updates to Adobe's Creative Suite 3 Web Premium edition, PhotoShop CS3 Extended cease to act like the PhotoShop program I have used for years. This is on a MacBook 2 GHz Intel Core Due with 2 GB RAM. Symptoms • Try to open an image file and PhotoShop crashes • Try to save a new file and PhotoShop crashes • Try to save an image opened in PhotoShop from Bridge and PhotoShop crashes self help After verifying the the disk permission did not need to be repaired and that the hard drive itself was fine, I reinstalled (repaired) PhotoShop CS3 and updated it. Same symptoms. And updating produced this error message: 'Updating cannot be applied to a product. Adobe Version Cue Client 3.1 failed to install. Reinstall the product and try again.' Reinstalling PhotoShop AND Version Cue produced the same error message and PhotoShop crashes. Adobe tech support • The first call to Adobe's Saturday tech support was useless. I will forgo the details here. • A search through Adobe's Knowledge base lead to a ten-page 8/10/07 Technote on ' Troubleshoot system errors or freezes in Photoshop CS3 on Mac OS.' Apr 26, 2008 - The other day, I started noticing a major problem with my Adobe Photoshop installation on a particular computer. Everytime I went to open an. Troubleshooting tips for system-related errors that occur when you use Adobe software on Windows. Troubleshoot Windows system errors, freezes| Adobe software. All Apps User Guide Select an article: On this page. Open the Adobe application folder on the desktop. After going through the beginning and some intermediate trouble-shooting steps, I stopped at #17 (Optimize hard disks) after reading Adobe's disclaimer about not supporting third party disk utilities. I haven't found a disk utility beyond Apple's Disk Utility that I trust. I finished my need-it-tomorrow photo editing and printing using Apple iPhoto '08 and decided to worry about PhotoShop on Monday. (iPhoto's a decent program, especially in a pinch.) • The second call to Adobe's tech support on Monday was also fruitless. I waited for 20 minutes in the 'long cue' to talk to Christopher who suggest that there might be a software conflict. He recommended that I try turn on the computer in Safe Boot mode (hold the shift key while turning the computer on) to eliminate software conflicts. Adobe Locks Up After OpeningAnd if that didn't work, create a new admin account and try a safe boot again, opening PhotoShop in the new admin account. I asked for a case number to avoid the long wait should I need to call back. Solution • The third call to Adobe's tech support on Monday was a bit frustrating, but did solve the problem. The frustration: my case number disappeared into the ether, so I had the long wait again, after an Adobe customer service rep verified my Adobe username and PhotoShop registration; he also provided my Adobe Customer Number - a good thing to know when you call Adobe's tech support. • I repeated everything to Joel who solved the problem and patiently answered all of my questions. He recognized this as a Version Cue issue and directed me to: Hard Drive > Library > Applications Support > Adobe > Abobe Version Cue CS3 > Client and had me move the 3.1.0 directory to my desktop. • I rebooted out of safe mode (no Internet connection to run an update) and updated the entire suit using Adobe Updater5 in the computer's Utilities folder. (Updater 4 was still there but we ignored it; Joel did not want me to remove it.) • While all the software was updated yet again, we talked about Version Cue long enough for me to realize that I did not need it. We also talked about plan C. Uninstalling the suite. Using Adobe's powerful clean up script, which sounded a little scary. We discussed the best way to uninstall the software - from the disk, not the uninstall utility, though I'm not sure why. • Thankfully, although there was an ambiguous error message, Version Cue seemed to update successfully. • Joel mentioned there was a doc on Adobe's site that dealt with this very issue: KB402521. Unfortunately, my 'search of Entire Site for KB402521 did not match any documents.' So I thought it best to blog this solution so it can be found. PhotoShop seems to work now. I opened, edited, and printed an image successfully. Adobe Reader FreezesI haven't verified all of the other programs yet, but I'm hopeful that they will work as expected. When I have some time, I plan to uninstall Version Cue. Hi Susan, My Photoshop CS4 begun to crash a few days ago, just after an update of the whole Web Premium suite from Adobe's server. I tried many fixes, taking inspiration from Google findings. One of the fix I tried was simple, aimed at 'giving what they wanted' to both the operating system or the Version Cue application. They wanted a file there, well I'll give it to them. But it didn't seem to work. Yesterday I wrote a request for help to Adobe, but they haven't answered me yet. Yesterday afternoon I got back to my work without Photoshop. Fireworks isn't that bad after all. And I was determined not to become hostage of Photoshop's fate. This noon(in Rome, which is GMT plus one hour time) I gave another try at Google, focusing on what I thought was the problem: a missunderstanding between Photoshop and Versione Cue. Very up in Google's list I find your article. It sounds so gentle. So I went back to my hard disk, looked another time to where these files needed by Version Cue should have been. I realized that I had copied the versioncue.dll files not in the 4.0.1 directory but in the Dictionaries subfolder of the 4.0.1directory. Gently, very gently I moved the files where they could do the magic and they did it. Photoshop is working properly now. Adobe Freezes UpI've updated the whole Web Premium with Adobe's server and it continues to work correctly. I'm still incredulous, but it looks as a stable fix. Thank you for the inspiration and the guidance, which worked well even in my environment: Photoshop CS4 on a Windows Vista operating system. Hello, I was so excited with this post! It looked exactly what i needed to fix my CS3 crashes. As I was online I did Daniel's hint to ' Indeed it is sufficient just to remove the 3.1.0 folder out of the directory and immediately run Adobe Updater5 (I also have 4 and 6 in Utilites folder) - it will download the Cue 3.1.0 Update and everything is fine now'.
