Write I/O errors on an active log data set

Symptoms
WebSphere MQ issues the following message:
CSQJ105E +CSQ1 csect-name LOG WRITE ERROR DSNAME=...,
           LOGRBA=..., ERROR STATUS=ccccffss
System action
WebSphere MQ carries out these steps:
  1. Marks the log data set that has the error as TRUNCATED in the BSDS.
  2. Goes on to the next available data set.
  3. If dual active logging is used, truncates the other copy at the same point.

The data in the truncated data set is off-loaded later, as usual.

The data set will be reused on the next cycle.

System programmer action
None.
Operator action
If errors on this data set still exist, shut down the queue manager after the next off-load. Then use Access Method Services (AMS) and the change log inventory utility to add a replacement. (For instructions, see Changing the BSDS.)
