I read too fast not realizing there were control paths on this library.
That'll be a problem. The control paths need like drives on them.
Partition the library with multiple control paths?

Jim,
Actually 2 LPARs.
2 577D, one on each LPAR.
All 4 drives connected to each 577D via FC Brocade switch.
The FC switch zoning below was given to by IBM years back.
SYSA IOPA Port1 sees both PORT5 TAPE1 and PORT6 TAPE2 SYSA IOPA Port2 sees
both PORT7 TAPE3 and PORT8 TAPE4
SYSB IOPB Port1 sees both PORT5 TAPE1 and Port6 TAPE2 SYSB IOPB Port2 sees
both PORT7 TAPE3 and Port8 TAPE4
then each system will see all 4 drives ... 2 drives per port of the IOA you
could leave all 4 drives with control paths ... or have only
TAPE1 and TAPE3 as the control path drives ... one per port minimum.

There should not be a problem. Are both drives connected to the same IOA?
There might be an issue there with the speed mismatch.

Is there an issue mixing LTO5 and LTO7 HH FC drives in the same 3573
library?
Power7-740-E6C.
Latest CUM and TR11.
All latest tape PTFs
Library is 3573
Latest library firmware - D.00 / 3.20e
LTO5 firmware - F991
LTO7 firmware - FA11
I received 4 new LTO7 HH FC drives.
Swapped 2 LTO5 with 2 LTO7 drives.
IPL IOP - 577D
INZBRM *Device
Library saw the 2 new LTO7 drives with no issue.
iSeries auto created two new 3580-997 resources.
Varied on fine
Added 6 new LTO7 volumes, no issue.
Tested BRMS control group save, no issue.
Near the end of the Auto Dup, received the below error, drive went to
failed status.
Message ID . . . . . . : CPF471E Severity . . . . . . . : 40
Message type . . . . . : Information

Message . . . . : Timeout on device TAPMLB01.
Cause . . . . . : A timeout occurred on device TAPMLB01. The timeout
origin
was either the Input/Output Processor (IOP) or the device.
Recovery . . . : Obtain the error information from the QSYSOPR message
queue. Fix the problem and attempt the command again.
Last week, our CE experienced a very similar issue at another site with
3573, LTO3 and LTO5 being swapped.
CE stated they reconfigured the library resolved the issue, not sure why.
Thank You
