Hello,
Recently my department had a SAN installed, and I am in the process of
setting up one of the first Linux machines connected to it. The machine
is running Red Hat Enterprise AS4 (x86_64), which uses Linux kernel
version 2.6.9-11.ELsmp.
giving more info about the infamous SAN would help :)
The SAN shows up twice in the kernel, as /dev/sdb and /dev/sdc. /dev/sdb
is inaccessible (I get a bunch of "Buffer I/O error on device sdb" kernel
errors), but /dev/sdc works fine. According to the administrator of the
it probably is a cheapo storage with an Active/Passive storage
controller, you cannot use md to handle those.
He told me to use PowerPath, but I'd rather not have to reinstall or
it is a long time i don't see powerpath on linux, but i am in favour of
ditching proprietary multipath solutions in favour of free ones.
what you want is multipath-tools http://christophe.varoqui.free.fr/
RH4 should already include a multipath-tools rpm.

Luca
