VMTHSC0697E causes HSC002 ABEND

Products

• VM:Tape for z/VM

Issue/Introduction

VMTAPE displays 4 ACSxxx locations (See Below) that are all part of a single SMC (VSM/HSC) setup. 

When I try to mount a scratch tape it causes an EJECT from Location ACS254 to get Loaded into ACS000 and this causes a failure and an HSC002 ABEND

Did I miss something? Not sure why VMTAPE is trying to EJECT the TAPE to mount it on the available drives (see drive locations below)

Resolution

The problem is all the TAPES are in ACS255, but all the DRIVES are in ACS254.
That's why VMTAPE asked for the volume to be ejected (from ACS255) ... in theory to have it moved to ACS254 so it could be mounted on one of (really then only) drives VMTAPE has in its configuration.

 

The simple solution to try first is to set AUTOPICK OFF...have VMTAPE ask the HSC to pick a SCRATCH tape based on the drives VMTAPE has.  Typically, this will resolve these types of problems.

 

 

Additional Information

Turning Off AUTOPICK resolved the issue for the customer.
