TSM Mirroring

[radhar]

Hi All,

We are planning to implement TSM mirroring for TSM DB and Recovery log. Could you please provide some pointers on how to implement TSM mirroring for DB and recovery log and also how to revert it back?

Thanks for your understanding and support.

Regards,
Rakesh.

öhm what did you mean with "implement TSM mirroring for TSM DB and Recovery log"?

normal db/log mirroring:

create db/log file
tsmserver: "def dbc [original db] [mirror db]" and def "logc [original log] [mirror log]"

What platform are you running on?

General steps:

1. Create the required space for the mirror (OS side)
2. Create the DB and LOG volumes - see "help define DBVOLUME" and "help define LOGVOLUME"
3. Define the DBCOPY volumes - see "help define dbcopy" for details
4. Define the LOGCOPY volumes - see "help define logcopy" for details

You are done. Just remember that if you have three DB volumes, you need three defined mirror DB volumes to have a full mirror of the database. This also goes for the log volumes.

To go back, just delete the mirror copy created in steps 3 and 4

Hi,

Thanks for your response..

TSM server is hosted on SUN SOLARIS 10. I hope DBCOPY and LOGCOPY holds good for this environment too.

Thanks for your assistance.
