Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

Type the following command on both nodes to determine the instance

numbers that the SCSI driver uses:

# grep sd /etc/path_to_inst | sort -n -k 2,2

Output from this command resembles the following on Node A:

"/sbus@1f,0/QLGC,isp@0,10000/sd@0,0" 0 "sd"

"/sbus@1f,0/QLGC,isp@0,10000/sd@1,0" 1 "sd"

"/sbus@1f,0/QLGC,isp@0,10000/sd@2,0" 2 "sd"

"/sbus@1f,0/QLGC,isp@0,10000/sd@3,0" 3 "sd"

"/sbus@1f,0/SUNW,fas@e,8800000/sd@d,0" 27 "sd"

"/sbus@1f,0/SUNW,fas@e,8800000/sd@e,0" 28 "sd"

"/sbus@1f,0/SUNW,fas@e,8800000/sd@f,0" 29 "sd"

In the output, the instance numbers are in the second field.

The instance number that is associated with the device name that matches

the name for Node A displayed in step 2, is "1."

Compare instance numbers for the device in the output on each node.

After you review the instance numbers, perform one of the following tasks:

■ If the instance number from one node is unused on the other— it does not

appear in the output of step 3—edit /etc/path_to_inst.

You edit this file to make the second node’s instance number similar to

the number of the first node.

■ If the instance numbers in use on both nodes, edit /etc/path_to_inst

on both nodes. Change the instance number that is associated with the

device name to an unused number. The number needs to be greater than

the highest number that other devices use. For example, the output of

step 3 shows the instance numbers that all devices use (from 0 to 29). You

edit the file /etc/path_to_inst on each node and reset the instance

numbers to 30.

Type the following command to reboot each node on which

/etc/path_to_inst was modified:

# reboot -- -rv
