virtual tapes changing formats?

[dynsbpa]

First, I want to say "THANKS!!!" to all that have developed and contributed to this awesome project!  I've only recently came across it and have been blown away by the capabilities.

I have been testing MHVTL with TSM 6.2 and have run into a brick wall.  Everything works wonderfully until I attempt a restore, at which time TSM states that it does not have drives configured for the tape format.  I've tried various setups using LTO3, 4 and 5 drives, all with the same result.  I have recreated my setup several times, being sure to match the VTL setup with the TSM setup (ie, LTO4 on MHVTL, LTO4 on TSM, etc).

When attempting the restore, TSM will offer up an error such as:  "ANR8484E No drives are available to be mounted in R/W mode with format ULTRIUMC in library VTL-LTO4."  In the proceeding example, everything has been configured to use only an LTO4 tape format.  The TSM error has varied in that sometimes it states it needs an ULTRIUM drive, other times that it requires an ULTRIUMC drive.

Within TSM, I have tried settings to allow the drive to determine the format as well as specifying the LTO format.  The restore test is nothing more that trying to restore what had been backed up just moments previously.  Has anyone else run into this or can anyone point me in a direction to resolve this?

Thanks in advanced!

Hi,

You need to use LTO1 tape drive and tapes due to a little bug with mhvtl and tsm and LTO2/3/4/5 tape drive + tapes.

Try this scenario and let us know.

Hi Crippa,

Your answer was right on the money.  I've stepped my library down to LTO1 and have not had any issue with mounting tapes for restores.  Onward with the testing!  

Thanks for the help, it is greatly appreciated!

You will need to use TSM mt driver for that and also device class of ECARTRIDGE

Thanks for the reminder :)

I'll attempt to get that mode page code 'Device Configuration
Extension mode page' implemented very soon.

Cheers

Just a quick update..

I've not forgotten this. Looking at the MODE sense/select I found I had to basically rework the whole code WRT MODE.
I'm in the middle of changing the MODE data as an array of data into a linked list.

I hope to have the changes ready some time this week.
