j. In cases where all the LUNs below the target port are put in authentication state, which
can happen when the target port was moved but the LUNs are same, then the target port
must be authenticated. Use the following command to authenticate a target:
# scsimgr -f replace_wwid -C tgtpath -I 3

The target instance can be obtained using the "ioscan -kfnNC tgtpath" command
k. You can change the DSF name to a new name or to an existing stale device using the
io_redirect_dsf command.
The following example shows the host converting /dev/disk/disk23 to the stale
/dev/disk/disk22.

or Application before changing the name. For details, consult the appropriate HP
documentation.
