Chapter 6 Measures in Abnormalities
III-111
The status waiting for faulty recovery continues until the fault recovers. To interrupt waiting for fault recovery,
perform interruption process on monitoring control screen on iSM client (after executing interruption, monitoring state
becomes “Stop (Fault)”).
For restarting the monitor function after recovery from failure, perform interruption process on monitor control screen
on iSM client and then start monitoring again.
If monitoring on a disk array discontinues due to problems with a management server (insufficient resources, etc.),
fault recovery is not waited for. In such a case, monitoring state becomes “Stop (Fault)”.

When Performance Monitoring, Performance Optimization, Replication or Snapshot operation fails, check the
following first.
• Was the product to use Performance Monitoring, Performance Optimization, DynamicDataReplication,
RemoteDataReplication or Snapshot purchased for the target disk array?
• You can check what has been purchased in Disk Array Properties in the Performance Monitoring screen on the
client.
• Is the process of Performance Monitoring, Performance Optimization, Replication or Snapshot running on the
machine where the iSM server is operating?
• Are there any forbidden operations done in Replication or Snapshot?

If any process of an iSM server has halted after the iSM server went operable, the iSM server autonomously restarts to
continue monitoring of the disk array. If an iSM client is used, connection is terminated so that re-connection is
required after the iSM server is operable. The iSM server attempts to restart up to five times in an hour. If the iSM
server is unable to restart at the sixth attempt, it stops or shuts down the current function.
If asking for a check on the fault, gather the fault information according to 6.1.9 “Information Gathering Method when
Server Fault with Unknown Cause”.
* The iSM server becomes operable after the message “iSM01002 Storage Manager is ready” is output.
* If the iSM server shuts down a function, the message “iSM01101 The function is not available.function=function-
name” is output.
The shutdown of an iSM server function means that the iSM server continues operation even if the target process (one
of the processes shown in the table below) is not operating. In this case, the function of the target process cannot be
used. If the process’s function is mandatory, stop the iSM server, check and eliminate the cause of the fault according
to the message, and then restart the iSM server.
