More than 7 LUNS per FC port

[Telia BackOffice]

Hi

Our backup team have bought a new Virtual Tape Libraray toy to play with. They have carved out 20 virtual tape drives and zoned them in to two of my servers. I only see 7 of these tape drives.

Googeling provided me with some hints that HPUX only supports 8 LUNs pr FC port. Is there any way to extend this?

HPUX 11.23 patched to latest quality pack and all that.

Best regards Thomas

I never worked with VLS yet, but according to the docs you will only see luns 0...7 for the virtual tape drives (this is different for disks!), see

I get a 404 on the page

The vendor of the VTL claims that it is due to the SCSI-2 protocol being involved. I know that scsi-2 is limited to 8 LUNs, but is this really the case, and if so, how do I verify this is the case and change it?

Shalom,

Your google search is correct. HP may be able to produce a patch for you. On this issue however, I'm waiting several years without results.
