3. Perform a configuration reboot:

[ACSLS_server]root:# ./reboot -- -r

▼Creating ACSLS host driver instances for virtual libraries

Once you have discovered the newly attached VTL virtual libraries, proceed as follows.

1.Log in to the ACSLS server as root.

2.Change to the the home directory of the ACSSS user, $ACSSS_HOME:

[ACSLS_server]root:# cd $ACSSS_HOME

The default location of $ACSSS_HOME is /export/home/ACSSS.

3. Quiesce ACSLS with the kill command:

[ACSLS_server]root:# ./kill.acsss

kill.acsss: Bringing down ACSLS

kill.acsss: ACSLS is down

A message that states that the PID file does not exist means that ACSLS was not running.

4.Obtain the World Wide Names (WWNs) for the remote Fibre Channel ports that connect the new virtual libraries. Run the cfgadm command with the show_SCSI_LUN option, and check the output for the WWNs of med-changerdevices:

The WWNs are part of the Ap_Id string, located between the controller number and the LUN number:

[ACSLS_server]root:# ./cfgadm -o show_SCSI_LUN -al
Ap_Id			Type	Receptacle	Occupant	Condition
c2			fc-fabric	connected	configured	unknown
