These messages tell you that a x'C2' (MEDIUM SENSE) command was
rejected by the device. MEDIUM SENSE is supported by 3590 tape devices
but not by older tape devices e.g., 3490. Either the executing program
erroneously issued the command to a 3490, the 3590 device is somehow
improperly defined to the system, some (ISV?) software caused a 3490
device to be improperly recognized by system code (even if defined
correctly), or the 3590 device is erroneously rejecting the command.
It could be that the executing program handled the command rejection
gracefully and moved on without problems. Nevertheless, I would not
ignore these messages. Something is wrong.
Ed is exactly right. The sense format, with the parentheses, is what
you get for a 3480/3490, so I assume that this tape is defined to the
system as one of those. As Ed said, the failing CCW (C2=Medium Sense)
is a 3590-only CCW
If you have the Zara tape management system, IBM documents a Zara bug in
info APAR II13360
Command Reject on 3480 with Zara Tape Management System
Following error is received :
IOS000I 0F8C,AE,CMD,C2,0200,,**,CM0774,SMFDUMPT 002
80407427000004200020(33E5000000000000)00F4(00000000)AF8F4544763
2CC00
Command reject on D/T3480 Tape due to C2 command incorrectly
being issued to a device that does not support that command.
The invalid ccw was being issued from module IFG019RM which was
being called with an invalid branch code from IFG0196T .
Relinking the ZARA exits with the current version of IFG019RB
corrected the problem.
Also, APAR OA08714 documents this same error in DFSMShsm doing an ABARs backup.
