Troubleshooting suspended pairs when using RAID Manager
The basic steps involved in resolving suspended volume pairs when using RAID Manager include:
•
Using the RAID Manager operation log file to identify the cause of the error.
•
Following the troubleshooting steps based on the SSB1 and SSB2 error codes (the codes are
recorded in the log file).
Location of the RAID Manager operation log file
The file is stored in the following directory by default:
/HORCM/log*/curlog/horcmlog_HOST/horcm.log.
Where:
•
*
is the instance number.
•
HOST
is the host name.
Error codes appear on the right of the equal symbol (=).
Example log file
Two error codes are included in this example (B9E1 and B901).
