If the command fails because of a failed disk, physically disengage the failed disk, but leave the disk in
the slot until a replacement is received.
◦
If the command fails because of an open CIFS session, check with the customer on how to close out
CIFS sessions.
Terminating CIFS can cause loss of data.
◦
If the command fails because the partner is "not ready", wait 5 minutes for the NVMEMs to
synchronize.
◦
If the command fails because of an NDMP, SnapMirror, or SnapVault process, disable the process. See
the appropriate Documentation Center for more information.
