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

Checking major and minor numbers for disk partitions

The following sections describe checking and changing, if necessary, the major

and minor numbers for disk partitions used by cluster nodes.

To check major and minor numbers on disk partitions

◆

Use the following command on all nodes exporting an NFS file system. This

command displays the major and minor numbers for the block device.

# ls -lL block_device

The variable block_device refers to a partition where a file system is mounted

for export by NFS. Use this command on each NFS file system. For example,

type:

# ls -lL /dev/dsk/c1t1d0

Output on Node A resembles:

crw-r----- 1 root sys 32,1 Dec 3 11:50 /dev/dsk/c1t1d0

Output on Node B resembles:

crw-r----- 1 root sys 32,1 Dec 3 11:55 /dev/dsk/c1t1d0

Note that the major numbers (32) and the minor numbers (1) match,

satisfactorily meeting the requirement for NFS file systems.

To reconcile the major numbers that do not match on disk partitions

Reconcile the major and minor numbers, if required. For example, if the

output in the previous section resembles the following, perform the

instructions beginning step 2:

Output on Node A:

crw-r----- 1 root sys 32,1 Dec 3 11:50 /dev/dsk/c1t1d0

Output on Node B:

crw-r----- 1 root sys 36,1 Dec 3 11:55 /dev/dsk/c1t1d0

Place the VCS command directory in your path. For example:

# export PATH=$PATH:/usr/sbin:/sbin:/opt/VRTS/bin
