[Jean-Yves Picard]

Hello,

short: How do I undo RH3 PSP 7.7 ?

Long version:
I have blade bl20g3 RedHat Update 2, which I want to connect to SAN. It work fine with venerable PSP 7.1.
The Driver is hp_qla2x00src-7.07.05.02-6, this driver came with a RH3 PSP 7.7 package, it can be isntalled fine if you installed it alone.
however, if you tried to install more of he PSP 7.7 package system crash at reboot.

How Can I undo PSP 7.7 ?
