Migrate from EMC powerpath to MPxIO.

As always use at your own discretion. I do not take any responsibility for any screw-up/data loss and please take a good backup

To migrate from Powerpath to Solaris MPxIO, the following steps can be used .This has been working on Solaris 10 with zpools on powerpath devices

Note: Take care when executing “stmsboot -e” on servers like v880/v890 which has fibre connectivity for internal disks.

Note1: If “stmsboot -e” is run on a server which has zfs boot (Solaris 10 10/08), during boot a scary message is displayed on console which   can be safely ignored ( at least for us until now)

  1. Remove the Powerpath package using pkgrm and reboot.
  2. The machine should come up without Powerpath
  3. Run “stmsboot -e -D fp” and follow prompts (Reboot required)

The system should come up with MPxIO enabled and the luns which are part of the zpools change their name from emcpowerXa to the MPxIO format.

If format does not show MPxIO multipathed disks … try adding the support for third party devices in the /kernel/drv/scsi_vhci.conf file. and rebooting the server again.
