To create a Read/Write copy of a single checkpoint:
fs_ckpt <ckpt_fs_name> -name <r/w_ckpt_fs_name> -Create -readonly n 

To export a Read/Write checkpoint copy to a CIFS Share:
server_export [vdm] -P cifs -name [filesystem]_ckpt1 -option netbios=[cifserver] [filesystem]_ckpt1_writeable1

To view HBA Statistics:
.server_config server_2 -v “printstats fcp reset”  Toggles the service on/off
.server_config server_2 -v “printstats fcp full”     View the stats table (must wait a while for some stats to collect before viewing)

To Join/Unjoin a CIFS Server from the domain:
server_cifs server_2 -Join compname=SERVERNAME,domain=DOMAIN.COM,admin=ADMINID
server_cifs server_2 -Unjoin compname=SERVERNAME,domain=DOMAIN.COM,admin=ADMINID

To view the current domain controllers visible on the data mover:
.server_config server_2 -v “pdc dump”

To enable or disable a domain controller on the data mover:
.server_config server_2 -v “pdc enable=<ip_address>”  Enable a domain controller
.server_config server_2 -v “pdc disable=<ip_address>”  Disable a domain controller

To stop and start the CIFS service:
server_setup server_2 -P cifs -o stop   Stop CIFS Service
server_setup server_2 -P cifs -o start  Start CIFS Service

To stop, start or check the status of the iSCSI service:
server_iscsi server_2 -service -start     Start iSCSI service
server_iscsi server_2 -service -stop      Stop iSCSI service
server_iscsi server_2 -service -status  Check the status of the iSCSI service

To enable/disable NDMP Logging:
Turn it on:
.server_config  server_x  “logsys set  severity  NDMP=LOG_DBG2″
.server_config  server_x  “logsys set  severity  PAX=LOG_DBG2″
Turn it off:
.server_config  server_x  “logsys  set severity  NDMP=LOG_ERR”
.server_config  server_x  “logsys set severity   PAX=LOG_ERR”

For gathering performance statistics:
server_netstat server_x -i               Interface statistics
server_sysconfig server_x -v         Lists virtual devices
