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)
