146 Continuous Access XP Journal

3.

Format the journal volume using the LDEV format function of Volume Management. For instructions on

formatting the volume, see the HP StorageWorks LUN Configuration and Security Manager XP User

Guide for the XP10000/XP12000.

4.

Register the formatted volume (or another volume that can be used instead of the formatted volume) in

the journal group (see ”

Registering journal volumes in journal groups

” on page 92).

• If you do not need to resume copying, the procedure is finished.
• To resume copying, continue to restore the mirror to which the journal group belongs (see

Restoring

mirrors (Pairresync: resuming copy operations)

” on page 104).

SIM reporting

The local disk array generates service information messages (SIMs) to notify you of possible disk array

service requirements. SIMs can be generated by the disk array’s channel and storage path

microprocessors and service processor (SVP). The SVP reports all SIMs related to Continuous Access XP

Journal processing. Each time a SIM is generated, the amber Message LED on the disk array’s control

panel (under the Ready and Alarm LEDs) turns on as an additional alert.
SIMs are classified according to severity for reporting and logging purposes: service, moderate, serious, or

acute. All SIMs are recorded on the disk array’s SVP and displayed on Command View XP computers or

XP Remote Control. You can find SIMs in the Command View XP or XP Remote Web Console Status pane.

SIMs the primary disk array generates include the primary data volume’s device ID (byte 13). SIMs the

secondary disk array generates include the secondary data volume’s device ID (byte 13).

NOTE:

For more information about SIM reporting, contact your HP account support representative.

If SNMP is installed and operational for the local disk array, each SIM results in an SNMP trap being sent

to the appropriate hosts. For more information about SNMP operations, see the HP StorageWorks

Command View XP User Guide for XP Disk Arrays or the HP StorageWorks XP Remote Web Console User

Guide, or contact your HP account support representative for assistance.

Figure 64

shows a typical 32-byte SIM from the local disk array. The six-digit reference code (RC) consists

of bytes 22, 23, and 13. The RC identifies the possible error and determines the severity. The SIM type

(byte 28) indicates the component that experienced the error. When the value of byte 22 is 21, the SIM is

a control unit SIM. When the value of byte 22 is Dx (where x is an arbitrary character), the SIM is a device

SIM.
