IC68505: QUERY PROCESS DOESN'T REPORT WAITING ON AN OUTPUT DEVICE CLASS

APAR status

• Closed as program error.

Error description

• When a device class mountlimit is restricted, query process can
  fail to report that is is waiting on the device class, if more
  mounts are required than the mountlimit allows.
  
  
  Customer/L2 Diagnostics:
  There are two copy storage pools both using a server device
  class that has a mountlimit of 1.
  When two backup storage pool processes need a copy storage pool
  volume mounted, using a server devtype device class, if a
  mountpoint for the server device class (mountlimit of 1)
  is in use, then the second process says it is waiting on a mount
  point for the primary storage pool input device class only,  and
  doesn't list the output device class name
  
  For example;
  q process
  
  Both copy storage pools use the same device class that has a
  mountlimit of 1.

Local fix

• Increase the mountlimit of the output device class to the number
  of mounts required at any one time, if the target server is
  capable of accepting this increase.
