ClearCase Server Migration

We moved our ClearCase to new server over the weekend, and copied the VOB to a new disk array. The VIP (scm0) of the server did not change. However, the server name changed from cbfe-dev-cm01 to clearcase1. We always use the VIP to access ClearCase. All the VOBs should be defined using the VIP.

After ClearCase was started, the cleartool desc command failed.

$ cat /ccstore/vobs/HealthCheck.vob/.hostname
clearcase1


The information in the vob_log is good enough for a solution.

$ cleartool unreg -vob xxx
$ cleartool reg -vob -host scm0 -hpath /ccstore/vobs/HealthCheck.vob /ccstore/vobs/HealthCheck.vob

$ cat /ccstore/vobs/HealthCheck.vob/.hostname
scm0

Everthing was fine after re-registery the VOB.
