SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

Wild-card characters are supported.
OUT file-spec
directs all SCF output to the specified file.
CLIM $ZZSTO.clim-name
is the name of the CLIM.
AWAY
specifies that all active paths using the specified CLIM be switched to inactive, if possible.
AWAY, FORCED
specifies that all paths using the specified CLIM be stopped. This may stop the last path to a
device. This command is useful prior to disconnecting a CLIM.
DEFAULT
specifies that all -P and -M paths using the specified CLIM be switched to active, if possible,
and all -B and -MB paths be switched to inactive, if possible.
DEFAULT, FORCED
specifies that all paths using the specified CLIM be started, if possible, before performing
switches to default active paths. This will not initiate a revive of a mirrored disk. This command
is useful after connecting a CLIM.
SWITCH CLIM Considerations
• The SWITCH CLIM command runs under $ZZSTO and initiates disk path switches for disks
configured through the CLIM. It sometimes takes paths up or down.
• If the SWITCH CLIM command is entered correctly, the Storage Subsystem Manager generates
an EMS message that reports the command, the time it was executed, the terminal from which
the command was entered, and the group and user numbers of the user issuing the command.
• Using wildcards in a SWITCH CLIM, AWAY command might produce unexpected results. If
the wildcard name matches CLIMs on both sides of a device, the first matched name will switch
usage away from the first CLIM, but unless you also specified FORCED, the second matched
name will switch usage away from the second CLIM and back onto the first CLIM. If you specify
FORCED, both paths to the disk will be downed and the device will become inaccessible.
• The $ZZCIP subsystem also supports a SWITCH CLIM command. For syntax, see the Cluster
I/O Protocols (CIP) Configuration and Management Manual.
SWITCH CLIM Examples
• Switch all paths that use S1002533 to inactive, if possible:
$ZZSTO 4-> SWITCH CLIM S1002533, AWAY
STORAGE E00096 Unable to perform 42 of the requested path switches:
$SAS01-B $ SAS02-B $SAS03-B $SASESS-B $SAS06-B $SAS07-B $SE08-P
$ZZSTO
5->
• Stop all paths that use S1002533:
-> SWITCH CLIM $ZZSTO.S1002533, AWAY, FORCED
• Switch all -P and -M paths that use S1002533 to active, and switch all -B and -MB paths to
inactive:
-> SWITCH CLIM $ZZSTO.S1002533, DEFAULT
SWITCH DISK Command
The SWITCH DISK command designates the active paths to a disk, as well as the preferred SAC
path for any disk accessible through dual paths. The syntax is:
