Notes:

If the DKC emulation type is I-2107, the setting of system option mode 308 determines whether the SIM is reported to the host,
as explained below:

When system option mode 308 is set to ON, the SIM is reported to the host.

When system option mode 308 is set to OFF, the SIM is not reported to the host. By default, system option mode 308 is set
to OFF.

Miscellaneous troubleshooting

Delta resync operation

If the status of the delta resync pair does not change after you performed delta resync operation,
some of the requirements and prerequisites may not have been fulfilled. In that case, after checking
the status of all pairs including the delta resync pair for clues into the problem, review all prerequisite
material in

“Delta resync configuration ” (page 144)

.

Suspension among journals

All the journals in a consistency group can be suspended when an error occurs in one of the
journals in the consistency group. This takes place under the following conditions:

The communications line between the RAID Manager and all primary systems are normal.

The status of the failed journal is PJSE or PJSF.

At least one journal in the consistency group is in normal status.

The following is provided for your information when the circumstances above are present:

When an error occurs, the status of the journal changes from normal to PJSE (suspended by
error).

For an error caused by overflowing capacity, status changes to PJSF.

When one journal becomes PJSE or PJSF, all other normal journals in PJNN status also become
PJSE status.

If you use RAID Manager and if a journal is in the normal status, it will be shown as PJNN.

Note that if some pairs in the journal become suspended by error but the whole journal does not
become suspended, the status of other journals will not change
