Hi All,
I have a Quantum scalar i40 tape library. I need to configure it to TWO tape partition libraries, e.g., library_a and library_b, so that each library has its own tape drive. Then connect this physical tape library to two different CentOS servers so that each server can see its own media changer and tape drive. I once had a successful configuration on one host but NOT on the other. One host sees the media changer and one tape drive, while the other host only sees the tape drive. After I delete tape partitions and re-create them both servers are totally screwed up. This is CentOS 5.7 kernel 2.6.18-274.
On one server:
# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: HP Model: Ultrium 5-SCSI Rev: Z58Z
Type: Sequential-Access ANSI SCSI revision: 06
Host: scsi0 Channel: 00 Id: 00 Lun: 01
Vendor: QUANTUM Model: Scalar i40-i80 Rev: 135G
Type: Medium Changer ANSI SCSI revision: 03

On the other server:

Can someone please help?
Thanks,
