Shalom,

Are you trying to boot of a SAN?

For whatever reason the kernel is no good. Drivers for the SAN don't appear to be properly compliled into the kernel.

SEP

[tkc]

boot back up from the existing kernel and check out what device is on h/w path 0/5/2/0. it may be due to the old kernel do not have appropriate driver or patches for the i/o device in this h/w path. you can try removing the adapter on 0/5/2/0 or device connecting to this path if you wanna try booting from the previous kernel.

[Lexxx]

How do I restart without checking this 0/5/2/0?? i remember in the config these are vg01,02,03.
I turned off disc enclosure for this path. How do I boot up without checking this path?
