I am reinstalling Sun cluster software after upgrading the OS to Solaris 10 from Solaris 9. I created a "/globaldevices" slice on the root disk of each node, installed Sun cluster 3.1 (latest one from Sun website). I then ran "scinstall" to add the new nodes and when asked, I chose to configure a quorum device later. After successfully adding the nodes, each node took turn to reboot. After booting up, I ran this command to get the DID device for quorum device in "scsetup" [root@comapp1]$ scdidadm -L 1 comapp2:/dev/rdsk/c0t256000C0FFC8455Bd1 /dev/did/rdsk/d1 1 comapp2:/dev/rdsk/c1t216000C0FF88455Bd1 /dev/did/rdsk/d1 2 comapp2:/dev/rdsk/c0t256000C0FFC8455Bd0 /dev/did/rdsk/d2 2 comapp2:/dev/rdsk/c1t216000C0FF88455Bd0 /dev/did/rdsk/d2 3 comapp2:/dev/rdsk/c2t0d0 /dev/did/rdsk/d3 4 comapp2:/dev/rdsk/c3t0d0 /dev/did/rdsk/d4 5 comapp2:/dev/rdsk/c3t1d0 /dev/did/rdsk/d5 6 comapp2:/dev/rdsk/c3t2d0 /dev/did/rdsk/d6 Both nodes that I run, it only showed the entries for comapp2, and nothing from comapp1. I think it must show entries for both nodes so I can pick one for the quorum device.
