Cluster Lock on new Storage or LUN
Hello,
We will be migrating our SAN this weekend, I still dont know what am I supposed to use for the LOCK device, right now we do have:
FIRST_CLUSTER_LOCK_VG /dev/vgdp
FIRST_CLUSTER_LOCK_PV /dev/dsk/c11t0d2
FIRST_CLUSTER_LOCK_PV /dev/dsk/c11t0d2
/dev/vgdp is a VG thats being used on the node that has the Data Protector package which uses /dev/vgdp
VG Name /dev/vgdp
VG Write Access read/write
VG Status available, exclusive
Max LV 255
Cur LV 1
Open LV 1
Max PV 16
Cur PV 4
Act PV 4
Max PE per PV 3473
VGDA 8
PE Size (Mbytes) 4
Total PE 13890
Alloc PE 11412
Free PE 2478
Total PVG 0
Total Spare PVs 0
Total Spare PVs in use 0
--- Logical volumes ---
LV Name /dev/vgdp/lvomni
LV Status available/syncd
LV Size (Mbytes) 45648
Current LE 11412
Allocated PE 11412
Used PV 4
--- Physical volumes ---
PV Name /dev/dsk/c8t0d2
PV Name /dev/dsk/c11t0d2 Alternate Link
PV Status available
Total PE 3472
Free PE 0
Autoswitch On
FIRST_CLUSTER_LOCK_PV right now is an alternative link, is this correct?
Anyways, I will be creating a new VG called vg_vgdp which will replace the existing /dev/vgdp and will be presenting NEW luns from a NEW storage to that VG, which PV or alternative link will I use for FIRST_CLUSTER_LOCK_PV on the ascii file? does it defer on each node?
THANKS!

Re: Cluster Lock on new Storage or LUN
While SAN Migraion you have to mention the disk details for the VG which was mentioned in cluster configuration file ..After migration the changed disk details need to be update.
