Subject: export import node metadata TSM database
Hi,
Is there any metadata of the exports stored in the TSM database?
==> Yes, the volser is retained in the VOLHIST file.
If I want to export eg two clients A and B to the same volume (eg a tape
vol001 that has enough space of course), can I specify twice the
command:
export node A filedata=backupactive devclass=<tape> VOL=vol001
export node B filedata=backupactive devclass=<tape> VOL=vol001
==> I don't believe TSM will let you do that; it SHOULD tell you that
vol001 is already in use.
Or must I specify
export node A,B filedata=backupactive devclass=<tape> VOL=vol001
to have both nodes exported to the same tape?
==> Yes, that is way to get both on the same tape.
And what if want to run an import of node B only for a restore from the
tape that contains the export of node A too with the command:
import node B filedata=backupactive devclass=<tape> VOL=vol001
Will it go directly to the point on the tape where the export of B has
been written or will it read the entire tape untill TSM finds the
beginning of the export of server B?
==> If you say
IMPORT NODE Devclass=<tape> VOL=vol001
TSM will import all nodes on the tape
If you say
IMPORT NODE B devclass=<tape> VOL=vol001
TSM will import only node B
As far as I know, TSM doesn't save any tape positioning information that
would let it skip to the data from B; I think it will read the whole
tape.
