Re: moving tape drives on vpar--URGENT

1-)If you have available scsi card on vpar3 that you can attach your tape, you can just physically attach tape to vpar3's scsi card and use ioscan to see the tape.

2-)If you have only one scsi card on vpar1 then you have to delete it from vpar1 and add to vpar3. To add or delete I/O resources the virtual partitions must be in the down state.


May be it is time to consider to use make_net_recovery...

Re: moving tape drives on vpar--URGENT

If this is internal it surely shares the LBA with disks - so no way to reassign it to another vPar without loosing the disks.

Consider to use an external tape or an ignite server!

Hope this helps!

Re: moving tape drives on vpar--URGENT

Hi,

If your tape is an internal one, I dont think it is easy. you need to analyse what and all the LBAs are assigned what are the devices connected to that LBA, it all will create very difficult situation.

Is your first Vpar is an Ignite server? If yes, you can take the backup of Vpar3 to tape drive of Vpar1.

Hello Trng

Cavdar is right

1) If you have multiple cards installed, then you can modify your vpar to assign each card to an vPar. This is just like having scsi card for each server (each vPar). In Vpars, devices are assgined at SBA or LBA/slot level.
If it is assinged at SBA level, then all of the belong to that Vpar, These can NOT be shared.

LBA of one vPar can NOT be shared by any other. These are dedicated.

You might Try,

export the Tape drive from the current vPar and mount it on the vpar3.

This may work.
