MSL 8096 Partitioned for VLS Smart Copy & Regular Backup, Restore

MSL 8096 Partitioned for VLS Smart Copy & Regular Backup, Restore

Have anyone used a Partition on MSL Libraries for VLS Smart Copy while using the other partition(s) for Regular Backup and Restore.

Is it a viable solution?

Hello Sunil,

According to the User Guide the destination library must be fully dedicated to VLS, and no other application/device should access it.

Please review page 77
http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c01869504/c01869504.pdf

"The destination library can only be used for copy operations"

I hope this answered your question.

I don't know that we have tested that exact configuration but that is exactly the type of use that partitioning is designed for.

From the perspective of the applications each has their own library with slightly longer move times. As long as the VLS Smart Copy reads the number of slots from the library instead of assuming a particular library type will have a hard coded number of slots there shouldn't be any problem.

I am going to give it a try. In a week or so I will be able to find out whether it works or not. Definitely this is an option that works in theory. I wanted to see if someone has already tried that out.

I will post an update after I have tried it.

This works well. The partitioned library is appearing in the VLS.

Good to hear.

Can you tell us what model VLS and backup application you are using? I would like to get a configuration with the VLS and a partitioned MSL into our normal qualification cycles. We might as well consider using a configuration that we know is a real customer configuration.

The only thing I can think of to watch out for is that the VLS automigration works best with a mailslot enabled and when the library is partitioned both applications share the mailslot. During export only the partition that performed the export can use the mailslot but during import it is up to the user to use the console for the correct application and import the tapes from the mailslot into the normal storage slots.

We, in this case, have MSL8096 with 4 LTO4 drives with two NSRs. Two drives connected to one NSR have been used for VLS SmartCopy. The Library has been partitioned into two. And we are using Data Protector 6.1.

I have attached a screenshot from the VLS automigration screen.

Are you running a multi-node VLS 9000 or Gateway? Or is this a VLS 6000?

Re: MSL 8096 Partitioned for VLS Smart Copy & Regular Backup, Restore

We have a VLS6636. I am sorry I missed it.

Thanks - I will get the config into the regular test matrix.

Could you tell me what version of firmware you are using? We are putting this configuration into a formal test cycle and will be testing the latest pre-release firmware but are going to test a release version as well.

There is a restricted build of VLS firmware with some improvements to Smart Copy. If you can send you email address to ltt.team@hp.com and request that the email be forwarded to me (name on this account) I can put you in touch with the people that manage that firmware.

Re: MSL 8096 Partitioned for VLS Smart Copy & Regular Backup, Restore

I am trying to setup VLS Smart Copy with VLS9000, MSL4048 and Data Protector 6.11. What login are you using in de client tab for the VLS? The documentation states to use the cimom_administrator login, but this does not work. The administrator login works, but I do not see anything under VLS Smart Copy. I am using firmware 3.2.1 with deduplication on the VLS.

Please post any new questions in a new thread with an appropriate title. Questions about cimom are unlikely to get answered hidden under a partitioning question.
