Powerpath upgrade from 5.5 P 01 (build 2) to PowerPath 6.0 P02

G'day. You will find details of the PowerPath configuration checker at https://support.emc.com/products/1767_PowerPath-for-Solaris/Documentation/ . Download the checker from here https://support.emc.com/search/?text=powerpath%20configuration%20checker&resource=ST&searchLang=en_US and run it against an emcgrab from the host you are going to upgrade. It will highlight any possible problems.

PowerPath has modules that link into kernel and user space. Always run an emcgrab and save the output file before performing any upgrades to a host that is connected to a DellEMC array or on a host that uses any DellEMC software packages. That will give you a reference point to "what was" before the upgrade. Perform your usual backup procedures so that you have a fallback position if there are any problems during or after the upgrade.

If your host is using ZFS export the pools before removing PowerPath vn 5 - see the section in the PP installation guide on PowerPath interoperability with ZFS file systems.

Reboot the host after the installation completes. If any problems occur run another emcgrab, open an SR  and attach the emcgrab taken prior to the upgrade and the emcgrab taken after the apgrade to the SR. We will help you troubleshoot and fix the problems.

Good luck....ian

Good morning,

Thanks for your advice. We finished the upgrade, following are the steps we performed.

• emcgrab and explorer output collected.
• /opt/EMCpower/bin/emcpadm export_mappings -f emcp_exports.txt
• /opt/EMCpower/bin/emcpadm import_mappings -f emcp_exports.txt ( Did not use it, kept as precaution)
• powermt check_registration ( Just in case if it ask for the License, emcpreg -install - to install the license )
• Shutdown the Database and Application ( 2 Solaris Zones)
• Shutdown the Zones.
• echo|format (output)
• Checked autoboot is false on both the zones
• powermt display dev=all ( to confirm the policy, symmopt, powermt set policy=so dev=all to set it back if there is any change)
• Gunzip, untar the powerpath
• pkginfo -l | grep -i emcpower*
• pkgrm EMCpower ( the server will ask for a reboot ## EMCpower successfully removed. Please reboot the host to complete the remaining steps.
• Reboot
• pkgadd -d EMCpower ( It will ask for confirmation and then it will upgrade with PowerPath 5.5.P01(previous) configuration). No reboot required.
• powermt version ( confirm)
• Done.
