UNCLASSIFIED
Hi all,
I have a linux system which has 10 luns from our SAN. Each lun has a
real path and 3 redundant paths. So, with 30 redundant paths, and what
looks like a 60 second timeout per path, this adds an additional 30
minutes to the boot up time.
As such, the users are revolting.
I think I've tracked it down to this udev entry:
/etc/udev/rules.d/50-udev.rules
ACTION=="add", SUBSYSTEM=="scsi" , SYSFS{type}=="0|7|14", \
RUN+="/bin/sh -c 'echo 60 > /sys$$DEVPATH/timeout'"
If I change that 60 to 5 or even 1, it would probably cut the boot up
time. But my question is: should I?
This is for RHEL 5.5 with Veritas Volume manager.
Another option is to use RedHat multipathing. But how does that behave
with veritas? Is anyone else running this configuration?
Thankx,
Greg.
