Consider the following points about the restoration of the DTACS file system. 

You need the following items: 

 

The tape from your most recent file system backup. 

 

An external eSATA/USB DVD-RRW drive, provided by Cisco (Addonics model 
AEPDRRWUE).

1.2.0.4/App release 1.2.0.7. 

 

A laptop with all required cables and connectors to access the iLOM/System 
console through the serial port. 

Important: Be sure your tapes are write-protected before you use them to restore the 
system. 

The script that restores the DTACS file system is called restoreFileSystems. You can 
run the restoreFileSystems script with the following options: 



(for example - /dev/rmt/0h) 

 

-r - Remote-tape-drive. Specifies a tape drive on a remote host computer. 
(for example - sparky:/dev/rmt/0h or 192.168.1.10: /dev/rmt/0h) 

 

-B - Backup directory. Specifies the directory that contains the backup from 
which the file system will be restored. The backup directory must be on an NFS-
mounted filesystem. 

 

-v - verbose. Verbose output. 

 

-i - interactive. Runs the restoration script in interactive mode. 

 

-h - help. Provides a brief description of the valid options. 

Note: The -l, -r, and -B options are mutually exclusive of one another; only one of 
them can be used.
