10.3 Backing Up a UNIX VOB with Remote Storage Pools

If a VOB has remote storage pools, its on-disk storage is probably not wholly contained within a single disk partition. It is quite likely that the storage is distributed among two or more hosts. Here is the procedure for this situation:

1. Lock the VOB.

2. Back up the VOB storage directory.

3. Back up some or all of the VOB's storage pools.

Use the lspool command in any view to determine which storage pools are remote, and their actual locations:

cleartool lspool -invob vob:/vobs/flex
13-Jan.16:58 vobadm pool "cdft"
"Predefined pool used to store cleartext versions."
26-Jan.22:02 vobadm pool "cltxt01"
"remote cleartext storage pool for 'flex' VOB"
13-Jan.16:58 vobadm pool "ddft"
"Predefined pool used to store derived objects."
13-Jan.16:58 vobadm pool "sdft"
"Predefined pool used to store versions."

In this example, there is one remote pool, cltxt01. If you are not sure which storage pools are remote, enter the lspool -long command to list the pool storage global pathname of every pool. Examine these pathnames to determine which ones specify remote locations:

cleartool lspool -long -invob vob:/vobs/flex
pool "cltxt01"
.
.
pool storage global pathname
"/vobstore/flex.vbs/c/cltxt01"
.
.

4. Unlock the VOB.
