Veritas VM/Cluster and A1000 failover on E4500

2007-12-25 1:23:00

Hi Managers/Gurus,

We have installed A1000 in failover mode connected to two E4500s . Now we are
going to create Veritas Volume with RAID 0+1 and will put under VCS.

But As per VCS doc we need to have the same major and minor nos. for NFS
failover to work. (Veritas Cluster Server 2.0 Installation Guide). I am very
much thankful to all who replied to me for changing the controller nos.
especially Darren DunHamm whose steps really helped me understanding How
controllers gets configured under Solaris. Now my problem is to set major and
Minor No. to be same on both sytems.

Following is the output of both system's A1000 Lun

System A

ls -lL /dev/dsk/c1t2d0s0

brw-r----- 1 root sys 189, 0 Mar 22 11:21 /dev/dsk/c1t2d0s0

lrwxrwxrwx 1 root other 44 May 26 23:02 c1t2d0s0 ->
..http://devices/pseudo/rdnexus at 1/rdriver at 2,0:a

System B

ls -lL /dev/dsk/c3t2d0s0

brw-r----- 1 root sys 196,1024 Mar 22 11:22 /dev/dsk/c3t2d0s0

lrwxrwxrwx 1 root root 44 May 31 23:17 /dev/dsk/c3t2d0s0 ->
..http://devices/pseudo/rdnexus at 3/rdriver at 2,0:a

As per the documentation we need to grep for instance according the device
output we got with

ls -l /dev/dsk/c3t2d0 But /etc/path_to_inst doesn't have any reference to
/devices/pseudo/rdnexus at 1/rdriver at 2,0 which is A1000 Lun device.

Cat /etc/path_to_inst
