Restoring a Solaris client with network boot
Note:
Review the secure communication compatibility support matrix for BMR table to know more about the supported master, boot server, client, and SRT versions for Linux, Windows, Solaris, AIX, and HP-UX environments. See Secure communication compatibility matrices for BMR for NetBackup 8.1.1 and later releases.
Note:
If NetBackup access control management is used in your environment, you must provide the appropriate credentials when prompted so that NetBackup can restore the client files.
To network boot Solaris clients, BMR requires the following:
PXE (In case of Solaris-x64 platform based client recovery)
DHCP
TFTP
NFS
To know more on the required network services configuration,
See Network services configurations on BMR boot Server.
Solaris system restore requires the name of the network device that directs the client to the correct BMR boot server.
After you perform the network boot procedure, the remainder of the restore process is automatic and requires no manual intervention. After the restore finishes and the client reboots itself, it is completely restored.
To restore a Solaris client with network boot
- Prepare to restore the client.
- Ensure that no other DHCP service except the one running on BMR Solaris Boot server is running in the same subnet. Otherwise the client DHCP boot request goes to un-intended DHCP server and network boot may fail.
Note:
This is a limitation with DHCP, PXE boot protocols themselves where first DHCP reply failure stops network boot process. Hence recommendation is to keep only Solaris DHCP service on the boot server running.
- Boot the client to restore.
- Terminate the boot process by using the #.command to return to the sc> prompt and send break command from sc>prompt to get OK prompt.
- Start the network boot by entering the following command
(net[id] is the device that points to the BMR boot server): boot net[id] where [id] is 1,2,3 interface cards.
- Start the network boot by entering the following command (net[id] is the device that points to the BMR boot server):boot net[id] where id is 1,2,3 interface cards.
Due to the automatic recovery parameter set during prepare to restore, the restore operation attempts to retrieve the host-ID based certificate and validate the Certificate Authority (CA) certificate. This recovery is time bound. For more information about the automatic recovery during prepare to restore, See Preparing a client for restore.
Note:
If you abort the restore operation or if the restore operation fails, either run the prepare to restore operation again to restart the automatic recovery or manually set the Allow Auto Reissue Certificate option using the NetBackup Administration Console or command-line interface.
For more information about manually setting the Allow Auto Reissue Certificate option, see Allowing automatic reissue of a certificate section within the NetBackup Security and Encryption Guide
After a successful completion of restore, the host ID-based certificate is copied on the client that is restored. The automatic recovery parameter is reset. For more information about the automatic recovery, See Preparing a client for restore.
