SNDA (ServerNet/DA)
The ServerNet/DA CRU (customer-replaceable unit) is an adapter that allows external storage devices to be connected
to servers. The external storage devices are physically connected to either Fiber SACs (
FSAC ) or SCSI SACs ( SSAC )
mounted on the ServerNet/DA CRU.

Actions
Replace
Launches the Replace SNDA guided procedure, which provides step-by-step instructions for replacing the ServerNet/DA
CRU.
Storage ASIC Initialization Test
Prompts the storage subsystem manager process ($ZZSTO) to initialize the storage ASIC in the CRU. If initialization
fails, an alarm is generated.
This action is triggered automatically when a new CRU is inserted while OSM is running or when an SCF STATUS
ADAPTER command is issued. If a CRU is inserted while OSM is not running, perform this action after logging on to
the OSM Service Connection.
Test Verify
Performs basic tests on the CRU. You can perform this action when the CRU is online.
