Pinned Track Recovery for TrueCopy Volumes

If a pinned track occurs on a TC390 M-VOL or R-VOL, the MCU will suspend the pair (SIM reference code

= D41x, D42x, DB1x, DB2x). Use the following procedure to ensure full data integrity of the volume pair

while recovering the pinned track:

1.

Connect to the MCU of the TCz pair that contains the volume with the pinned track, and select the

correct CU image.

2.

Delete the TCz pair that contains the volume with the pinned track.

NOTE:

If you delete the TCz pair containing the volume with the pinned track, delete only the pair

containing the volume with the pinned track. To delete only the TCz Asynchronous volume pair

containing the volume with the pinned track, select Volume for Asynchronous Parameters and

Delete Range.

3.

If the volume is offline (for example, R-VOL has pinned track)), vary the volume online.

4.

Perform your usual procedure for recovering data from a pinned track. Refer to the pinned track

recovery procedures for your operating system. Contact your HP account support representative to

inform them of the pinned track.

5.

If the volume was previously offline (for example, R-VOL), make sure to vary the volume offline again.

6.

Restart the volume pair using the Add Pair window, making sure to use the Entire initial copy option.

NOTE:

Be sure to specify the volume pair for which the pinned track recovery operation was performed.

SIM Reporting

The XP128/XP1024/XP10000/XP12000 reports a service information message (SIM) to the host when it

is necessary to notify the user of a possible service requirement for the disk array. The SIMs are classified

according to severity for reporting and logging purposes: service, moderate, serious, or acute. The SVP

reports all SIMs related to TC390 operations and all SIMs are stored on the SVP for use by HP personnel.

The SIMs reported to the zSeries and S/390 host are logged in the SYS1.LOGREC dataset of the host

operating system. Each time a SIM is generated, the amber Message LED on the

XP128/XP1024/XP10000/XP12000 control window (under the Ready and Alarm LEDs) turns on as an
