[rahulpawar]

Dear Friends,

We have TSM server installed on Aix os.

My 4 db volumes are mounted on 4 different file system in aix.

Now i want to move that 4 volumes into single VG ( In single file system)

​

How i can do it?

Please help me

Hi

Assuming you have new storage for this:

Create your new volume group and filesystem
Define new DB volumes in TSM on the new filesystem using "define dbvol"
delete the old db volumes in TSM using "delete dbvol"
(TSM will automatically move the db data from the old volumes to the new ones)
delete the old filesystems
delete the old volume groups.


Hope that helps

Db vol deletion

Thanks for your reply

Can u please tell me how tsm will move database from

the previous file system to new file system.

And if i delete the db volume then will it delete the dbdata.

No need to move your DB; define the new db volume in TSM. Then make a "del dbv" - TSM will "copy" the "old data" to your new db volumes.

Actually i am doing this activity on production,

NO!

ok!
create new dbvolumes with "dsmfmt"
do a "def dbv [path]" in the dsm commandline to define your new dbvolumes
do a "q db"
do a "q dbv" to if your new dbvolume is created and defined/usable
(you will see, that your "max reduction size" will grow)
now you can do a "del dbv [old path]"
(this will take a while) ... tsm will delete your old dbvolume and from now! tsm uses your new dbvolumes.

do you have also some mirrored dbvolumes? (q dbv)

 

[toxy13]

ok, you can do dsmfmt, q db, q dbv and post your output!

Build yourself a test TSM server instance if you feel you need to practice this sort of exercise...
