Bakcupexec vs LTO Drive

Created: 18 Jul 2013 | 9 comments

I like to know if Backup Exec can manage two LTO Drive in the same tape library (IBM TS 3100) if i have one drive LTO 3 and one LTO 6

J'aimerais savoir si backup exec peut gérer un drive LTO3 ET LTO6 dans la même librairie de tape (IBM TS 3100)

Yes, it is possible.  You will want to use bar code rules or partitioning (software or hardware) to keep the right media going in the right drive since there is no media that works with both drives.

If you find this is a solution for the thread, please mark it as such.

Partitioning will not prevent the wrong tape from being used in the wrong drive, e.g. LTO3 tapes used in the LTO6 tape drive.  There are many discussions in the past which will attest to this fact.

The only way to prevent this is to set barcode rules.  See my articles below

Note that your tapes must be using barcode labels.

Hardware partitioning will most definitly keep the LTO3 tapes from being put in the LTO6 drive and vice versa.

Software partitioning will keep the LTO3 tapes from being put in the LTO6 drive and vice versa for BACKUPS.  Yes, there are known limitations for utility jobs like erase, etc where the wrong tape can get put in the wrong drive, but no damage is done, it is just an inconvenience.

Using bar code rules is a perfectly good solution for most people.

No, BE isn't aware of it, since it is done at the hardware level.  BE would see this as two separate libraries.

I think the OP's library supports hardware partitioning, but I haven't verified it.

I haven't heard of anybody having issues unique to hardware partitioning.

From the BE HCL:

Partitioning a library using the library management for sharing between applications and/or servers is a hardware specific feature available in certain library storage systems. Customers using this hardware feature with Backup Exec are supported, but due the variations in design and implementation, technical support is provided in a "reasonable effort" basis only. This means that Symantec Technical Support will work with customers to resolve issues associated only with the Backup Exec portion of the shared configurations, and any issues that cannot be duplicated outside of the shared environment will be the responsibility of the OEM hardware vendor to support.

In not so many words, partitioning will not work for the user.

...and I assume you have the relevant Library Expansion Option license installed or the 2nd tape drive won't work at all!

Thanks!

The 2nd drive is not install yet. I just want to know if it's possible to make that work?

Thanks for the answer i will try it with the bar code rules
