SG Lock Disk & Persistent DSF

[Pedro Cirne]

Hi,

I'm having an issue with the lockdisk because the PDSF is not equal on both nodes for the same phisical disk:

root@porsx022:/etc/cmcluster# ioscan -m dsf /dev/disk/disk84
Persistent DSF Legacy DSF(s)
========================================
/dev/disk/disk84 /dev/dsk/c7t2d2
/dev/dsk/c9t2d2

root@porsx023:/var/adm/syslog# ioscan -m dsf /dev/disk/disk83
Persistent DSF Legacy DSF(s)
========================================
/dev/disk/disk83 /dev/dsk/c7t2d2
/dev/dsk/c9t2d2

What would be the best way to correct this situation?

Hi Pedro,

i think it is not an issue as long as you know that the disk is same, you can enter the DSF name for both the server.

you have to specify the decice files for lock disk for each server in the cluster. It does not matter if device files are differnt. what matters is that disk should be the same.

I have done it in my cluster environment and it is working fine here.

Hi,
It doesn't matter if the device files are diffrent(as long as the lun is same). only thing you need to mention the correct device file in the ascii file with respect to the node.

Thanks & Regards,
