Determining which resynchronization recovery procedure to use Determining which recovery procedure to use involves analyzing the information in the system information messages (SIM) and path failure system messages to determine if all of the conditions required to use resynchronization exist, then selecting the procedure to use. You select the procedure to use based on a number of factors, including the continuation of host I/O, failover, and the status of the secondary volume. Prerequisites Make sure you have identified the type of failure that occurred by using the system information messages (SIM) and path failure system messages. For more information, see "Using system messages to check for failures". NOTE: The procedures for RAID Manager and RWC are the same. Recovery from failures using resynchronization 63

Determining which resynchronization recovery procedure to use
Determining which recovery procedure to use involves analyzing the information in the system
information messages (SIM) and path failure system messages to determine if all of the conditions
required to use resynchronization exist, then selecting the procedure to use.
You select the procedure to use based on a number of factors, including the continuation of host
I/O, failover, and the status of the secondary volume.
Prerequisites
Make sure you have identified the type of failure that occurred by using the system information
messages (SIM) and path failure system messages.
