Moving from EMC PowerPath to MPIO on HP-UX 11.31

[Kennedy G. Doss]

HP-UX Admins,

                   If I have to eliminate PowerPath and make use of native MPIO, are there any documents, pointers, technical instructions somewhere which you can send me? Any input would be most appreciated.( I am familiar with the steps needed to move from EMC PowerPath to native MPIO/Multipathing in the  RHEL world. I've never done that before in the HP-UX environment)

Regards,

-Kennedy

You're going to want EMC Host Connectivity Guide for HP-UX to cover the details. It's available on EMC PowerLink. The current version is September 2011.

Hi Kennedy,

Just follow these two attached docs which explains step by step instruction on how to configure Native MPIO in HP-UX to work with Storage Array. I was successfully configured three of our RX6600 IA64/HP-UX 11.31 server with EMC Clariion array.

If you have PowerPath you would have to export the VG, remove powerpath & then import the VG. Note that the export will remove the VG so do this with caution. I would try on a test environment first.

# vgexport -m /tmp/vgev01.mapfile -s -v /dev/vgev01

Here's how to remove PowerPath:

# swremove -x autoreboot=true -x mount_all_filesystems=false EMCpower

Re-create and it will use the persistent names of the disk devices.

# mkdir /dev/vgev01
# mknod /dev/vgev01/group c 64 0x200000
# vgimport -m /tmp/vgev01.mapfile -s -N -v /dev/vgev01

thanks,
