No Available Tape Library Drives
To see the specific returned error, use a STATUS TAPEMOUNT, DETAIL command:
MC>STATUS TAPEMOUNT,DETAIL
Tape Mount 648
Tape Name *RETRY
Action NO ACTION NEEDED
Write Protected NO
Label Type ANSI
AVR System \SYS01
Tape Use OUT
Open Exclusion EXCLUSIVE
Comment ZSSI ERROR 57, WILL RETRY
Process Name $Z723
Process (CPU,PIN) (5,165)
Define Class TAPE
Define Name =DEF
Program Name \SYS01.$SYSTEM.SYS02.FUP
1 tape mount returned.
The COMMENT field returns the specific ACSLS library server error. The EMS
message generated by ZSSI has error text corresponding to the error. For a
description of the error and recovery, see your ACSLS library server error manual.
No Available Tape Library Drives
If all tape drives in a tape library are unavailable, $ZSVR generates an EMS event
containing tape server process error 1013 (all tape drives busy, queueing ACS
request). After a three minute delay, it retries the request. If a MEDIACOM STATUS
TAPEMOUNT command is executed during this three minute interval, this is returned:
MC>STATUS TAPEMOUNT
Tape Tape Label Write
Mount Name Type Node or Device Prot Action Needed
----- ------ ------ ---------------- ---- -----------------
648 *BUSY ANSI \SYS01 NO NO ACTION NEEDED
1 tape mount returned.
*BUSY, returned in the tape name field, is used to distinguish this type of request.
When the request is retried, the tape name becomes *ZSSI. See the example in
on page 8-8. If you determine that the request should not be retried,
use the REJECT TAPEMOUNT command to cancel the request.
Nonretryable Errors
If a nonretryable error is returned from the ACSLS library server, the requesting
application's OPEN request fails with file-system error 595 (a nonretryable error has
occurred), and $ZSVR generates an EMS event containing tape server process error
1012 (SSI non-retryable error).
