Hi,
This is a sample of custom UDEV(7) rule for Thumper(X4500)''s 48 disks.
Traditionally, the disk device name on the linux is assigned to sda, sdb,...
But, this udev rule is helpful to access as solaris map on Thumper. This means
you can access Thumper''s disks using c0t0d0s0, c1t0d0s0 device name on
the linux..
You just copy 99-dsk.rules to /etc/udev/rules.d and minus-1.sh to
/etc/udev/scripts
then run udevstart. After that, the device links are created under /dev/dsk
directory
and it should be accessible. This is also helpful to easy create the Linux RAID.
e.g) create the MD across the 6 different contollers
mdadm -C /dev/md11 --run -l 5 -n 6 -c 256 /dev/dsk/c{0,1,4,5,6,7}t1d0
So, this rule file is one of sample to access with "solaris like device
name" on
linux, but of course, you can name any names with custom as well :)
Thanks

I''m not intimately familiar with udev rule writing, but do you really have to list one line per SCSI device? Can you not write a script that you can put on a single udev line that will create the dsk/c?t?d? pattern such as: BUS="scsi", KERNEL="sd*[a-z]*", PROGRAM="/etc/udev/scripts/minus-1.sh %n", SYMLINK="..." and get a reference back from the script for the SYMLINK? I think the variables such as BUS, ID, etc. are available to the PROGRAM. b. -------------- next part -------------- A non-text attachment was scrubbed...

Brian, Yes, I understood that you mentioned below. Each "ID" are referring to directory of /sys/bus/scsi/devices/X:0:0:0. Probably, we might be possible to reduce the lines well. But, this was easy way to make 1:1 mapping same as solaris like device and this rule is used many sites as the production today. So, I think, we''d good to start from this rule to get in out stack, but we will need to improve this rule to be simple and flexible in the future. Thanks -Ihara Brian J.
