What os are you using.
Which tape library?
Which firmware level are you using in the lto-5.

Subject: [Veritas-bu] IBM LTO-5 (8.0gbps FC) / QLogic 2562-CK (8gbps HBA) timeout question
Hi,
Was curious if anyone had been running into timeouts with IBM LTO-5 drives in heavily utilized environments with QLOGIC 2562-CK (8GBPS) HBAs?
Never saw this in smaller environments with MPX <= 3 but now with MPX >= 6 some drives seem to be timing out and going into a “hung” state.
Was curious if anyone ever ran into this issue before?
Power cycling the drive (reseating it) fixes it and then it’s fine again as a workaround but not a fix, thoughts?
F/W on the IBM LTO-5 drives is BBN2 (latest from Oracle)
F/W on the HBA’s is 3.00 (latest from QLogic)
When the problem occurs (these errors spew continuously) until the drive is reseated (rebooting the robot does not clear out the errors)
