24.7.12 Actions following an error

After a copy process fails, the contents of the GDS volume of the backup source or the backup destination maybe invalid. Cancel the backup relationship, correct the problem causing the error, and then restore the backup relationship. The following procedure explains the process.

24.7.12.1 Retaining Informational and canceling the backup relationship

The backup relationship is canceled by using the sfcproxybreak(1M) command. The following explains how to collect the configuration information before canceling the backup relationship.

The following information is needed to restore the backup relationship.

(1) Relationship name

(2) EC employmentor OPC employment

(3) Correspondence between partitions or group

The backup relationship information can be saved by directing the output of the sfcproxyinfo -f command to a file. The information will be needed to recreate the backup relationship after the problem causing the copy failure is corrected.

The following is an example of saving the configuration information by using the sfcproxyinfo(1M) command.

# sfcproxyinfo -f backup1_for_volume0001 > /var/tmp/relation_backup

For details, see "24.7.9.1, Canceling the backup relationship." The relationship can be canceled with the volume locked on other nodes.

24.7.12.2 Recovery from an INVALID state

For details on recovery from an INVALID state refer to "Appendix F.1 Resolving Problems" in the "PRIMECLUSTER Global Disk Services Configuration and Administration Guide."

24.7.12.3 Recreate the backup relationship

The configuration information that was saved by the process in "24.7.12.1 Retaining Informational and canceling the backup relationship" is used to recreate the backup relationship.

For details on the setting method of correlation, see "24.7.7.3 Setting up the backup relationship."

The following example uses the file /var/tmp/relation_backup to recreate the backup relationship between the backup source and the backup destination.

# sfcproxyjoin equivalent -r backup1_for_volume0001 -f /var/tmp/relation_backup
