Displaying Information About Connections to SACs
on an FCSA
•
Operational firmware downloaded through a REPLACE command does not remain
in effect beyond the next system load. A system load reverts to the standard
firmware file names in the specified SYSnn.
•
Flash firmware replacement is permanent until the next replacement.
•
For operational firmware, you can use the CPU attribute or the ABANDON attribute
to have different SACs use different versions of the same firmware type. After
determining which version you want, use the REPLACE command to download the
chosen version to all SACs that use that firmware type.
•
For operational firmware, a complete download from all CPUs on a 16-processor
system takes at least 8 minutes.
Displaying Information About Connections to SACs on an FCSA
You can use the STATUS SAC command to display current status information about
connections to a SAC on an FCSA, including worldwide names and available LUNs.
For details, see STATUS SAC Command on page 14-123.
You can use the STATS SAC command to display statistical information about the
connections to a SAC on an FCSA. You can get information about a port in the Fibre
Channel link or the SAC itself. For details, see STATS SAC Command on page 14-116.
Testing Connections to the SACs on an FCSA
You can use the PROBE SAC command to test the connection to a SAC on an FCSA.
The connection can be either an arbitrated loop or a link to a Fibre Channel switch. For
