Dear Veritas Users,
I am confronting a problem on a Veritas Cluster node. I have expanded the storage (SAN) of a DiskGroup on a cluster node. Actually I must have to scan the both nodes with the help of following commands, before expanding the DS on the running node. I forgot that and did the whole work only on the present running node.
update_drv -f sd
devfsadm -Cv
cfgadm -al -o show_FCP_dev
vxdctl enable
As I noticed my mistake I have done the required job on the second node (not active node) too. But I have a discrepancy in the output of the command "inq -nodots"
Active Node (Running at present with the extended memory)
#inq -nodots | grep -i 436
/dev/rdsk/c3t5006048452A52BA6d136s2 :EMC :SYMMETRIX :5771 :9800436000
/dev/rdsk/c4t5006048C52A52BB3d136s2 :EMC :SYMMETRIX :5771 :9800436000
/dev/vx/rdmp/EMC1_65s2 :EMC :SYMMETRIX :5771 :9800436000
Backup Node
inq -nodots | grep -i 436
/dev/rdsk/c3t5006048452A52BA6d136s2 :EMC :SYMMETRIX :5771 :9800436000
/dev/rdsk/c4t5006048C52A52BB3d136s2 :EMC :SYMMETRIX :5771 :9800436000
As you see, the backup node has no information of the system disk (SAN-Memory). That's mean, in case of a swing over to the backup node, the Veritas Cluster will not function properly.
I hope, I could explain the problem. Can any body help me to solve this. If the description of the problem is not enough good, I can try to explain it again.
Thanking you in anticipation and waiting for your help anxiously,
Naeem Sheikh
Mit freundlichen Grüßen
Naeem Sheikh
