4.6.3 Recovery

This description assumes a system disk which is restored from a tape device (DAT drive)
which is connected to the system console (SMC).
Restoring a file system
A file system is restored with the command ufsrestore.
The following description shows how the file system is restored from the remote tape device
of the SMC with ufsrestore.
Preparations
1. Enlist the server name and root which execute the restore process in the file /.rhosts
of the system console and permit remote access.
Example: <partition-name> root
As an alternative, keys can be used in the framework of the Secure Shell.
Procedure
1. In the partition which is to carry out the data recovery, the Solaris operating system is
now started via the network from the system console:
{0} ok boot <LAN controller> -s
Here <LAN controller> is the alias name of the system console LAN controller. The
alias names can be checked in OBP using devalias.
As of the SX140 model series the alias names net and obp-net can be used by
default. As default on SX130 servers these alias names are net<x>, where <x> is the
number of the system board whose onboard LAN interface is connected to the admin-
istration LAN. For SX130 servers this is 0, 2, 4 and 6 consecutively from the left.
2. Activate the network:
# /etc/init.d/inetinit start
3. Start the RPC service:
# /etc/init.d/rpc start
4. Activate the network interface:
# /etc/init.d/inetsvc start
5. Mount a new file system at a temporary mount point:
Example: # mount /dev/<device-name> /mnt
