The following troubleshooting tables help you identify and correct problems that can
occur when you install the modular tape subsystem. Each table addresses a specific

described in the 6760 ServerNet/DA Manual.
2. Use the SCF STATUS ADAPTER, DETAIL command to check the status of all
paths to the adapter and its attached devices.
