AIX: Powerpath upgrade
Hi! I'm trying to upgrade PowerPath from 5.3 SP1 to 5.5 P01.
before:
> powermt version
EMC powermt for PowerPath (c) Version 5.3 SP 1 (build 84)
after:
> powermt version
EMC powermt for PowerPath (c) Version 5.5 P 01 (build 1)
setup:
-boot on SAN plus one datavg
-AIX 6.1 TL06
After reading the doc:
-varyoffvg datavg
-pprootdev off
-reboot
After reboot, only thing up is rootvg datavg is still varyoff.
Unfortunetly, I get this error message when I try to upgrade PowerPath... (smitty update_all)
UNABLE TO UNINSTALL DRIVER: see Installation Guide for instructions
Failure occurred during pre_rm.
Failure occurred during rminstal.0
But if I try a second time right after first failure, it now works...
I've tried this procedure many times with different servers and it's the only way I can make it to work.
Can someone help?
