TSM - change diskpool from internal server disk to Storage

Hello,

I'm running a TSM 7.x with fibers connected strait to TS3200. The diskpool are on inside server disk.

But, I need to reconfigure it to use a storage, in which I'll be able to get more disk space, speed and be safer.

The question is, I'm struggling on IBM manuals to figure out how to do it. For sure it isn't just to change the connectors...

So, if any one who can help me to find the right literature or on the steps on doing it, I'll appreciate, thanks in advance!!!
Eduardo

What type of pool is it?
  1. - random disk pool
  2. - file pool without dedup
  3. - file pool with dedup
  4. - directory container pool
The instructions will vary depending on which one it is. I think you mean 1, but I want to be sure otherwise the results could be catastrophic.

Hi Marclant,
I'm not sure but the "q vol" shows:
Code:

Hi,
Simple solution:
- Attach new storage (say it ends up as f:)
- Grant tsm access to folders
-From dsmadmc:
* define vol DISKPOOL f:\diskpool\disk1.dsm f=49152
* define .... disk2....
* upd vol e:\diskpool\disk* acc=reado
* mig stg diskpool lo=0
* wait for volumes to emptyl
* del vol f:\diskpool\disk1.dsm

Check that no volumes exist on f:\diskpool\

dsmadmc q vol f:\*

Delete old files

Thanks Trident and Marclant!!!

Sorry, but I've became a bit confused.
Yes I have a tape poll(TS3200 - with 43Tapes). The diskpool receive the backup from clients, than it is migrated to tapes.

Trident,
let me see if a understood what you said!!!


Attach new storage (say it ends up as f:)

Not sure if it will be so ease as this!

-From dsmadmc:
* define vol DISKPOOL f:\diskpool\disk1.dsm f=49152

Ok, ponting to (new) f:
f=49152 - does it means ~50GB?
* upd vol f:\diskpool\disk* acc=reado

Read only, sure?
* mig stg diskpool lo=0
Ok !
* wait for volumes to emptyl
OK!

* del vol f:\diskpool\disk1.dsm
Should I delete the new created f:\... disk1.dsm in the end?

PS: in order to get the storage working and connected to the server do you think it's all about just change the fiber connections?

Thanks !
Eduardo

No, it is 48Gb = 48 *1024 =49152 Just a nice logical size


* upd vol f:\diskpool\disk* acc=reado

Read only, sure?
No, that was a error. It should be e:, where the old volumes exist

* mig stg diskpool lo=0
Ok !
* wait for volumes to emptyl
OK!

* del vol e:\diskpool\disk1.dsm
Should I delete the new created f:\... disk1.dsm in the end?

No, that was also a typo from me. You should delete the old volumes from TSM, the from the OS.


PS: in order to get the storage working and connected to the server do you think it's all about just change the fiber connections?

Thanks !
Eduardo
Not sure what storage you have in mind. You need to supply more info about how it is connected before we can give a suitable answer.

No, the original local volumes that you no longer want to use.

PS: in order to get the storage working and connected to the server do you think it's all about just change the fiber connections?
Fiber connection and configuring the disk at the OS level. You can only configure it in Spectrum Protect once the OS has a drive letter or a mountpoint and you can read/write to it.

Might want to create more than one LUN too for the storage pool if this is going to be a busy server. Example: F:, G:, H:, I:. Or create mountpoints: instead: C:\Diskpool\disk1; C:\Diskpool\disk2, ...

I personally prefer mountpoints, you can create human readable names that mean something, with drive letters, it's not very descriptive.

Great!!
I'll check the storage type/model and the available amount for the bkp tasks. Also, how connections are/will be made.

Thanks again!

Hello !!
Yes!
My TSM server(jacaranda) have now a disk "F:" with 2 TB, created to be used as the new "diskpool".
Some questions:

How to know if tsm have grant access to disk/folders?

The 48GB amount, for each "disk.dsm" looks like a good size for my actual diskpool. Fof the new one(2TB) it could be better to create bigger ones, about 102.400GB, and handle with less "disks"?
Where:
100*1024 = 102,400 GB
2,000,000 / 102,400 = 19 disks or volumes

I really don't know what is the best approach for the TSM on the matter. Bigger files or more files...

So, that's it!

Set the acl on the top directory where tsm will write. Make sure the instance user can read/write/create/delete files

As of the size of each volume, it may vary. I have usually 16Gb volumes for my 'Diskpool'.

Instead, I would login to Windows as the Instance owner, and have that create the necessary directory folder. That way, the instance owner will also be the file/directory owner.

Thanks !

I've made a test and "define vol DISKPOOL f:\diskpool\disk1.dsm " just succeed !! The new file are there !!
So, I'll create all ones with 102,400GB, upd for r/w, and start a migration after that.

May I have to stop session, migration and so on?
