Hi all,

client is Solaris 10

SRT created in Solaris boot server in different subnet

I'm trying to restore the client from the boot server after starting prepare fo restore from master server.when I'm starting boot  from net (boot net) in the client machine it  not connecting to the boot server.

I tried to restore from the CD ROM but unfortunatly at the beggining it read from the CD thin it failed because of hardware fail.kindly suggest how to restore from network.

Regards,

Hello, can you provide further details regarding your problem? The network boot requires both client and boot server reside on same subnet for solaris, does this hold true in your setup? If so, ensure there are no other servers responding to your client boot request, maybe a jumpstart server on your network.

For Solaris, the boot server has to be in the same subnet as the client.

from the BMR manual (7.5)

 

Each network segment with Solaris clients must have a SolarisBMRboot server that can support
the clients.
However, you can use the following to minimize the effect of this requirement:
■ When necessary, you can install BMR boot server software on a Solaris computer in the
network segment. Then create an SRT after the client has failed and needs to be restored.
■ The Solaris BMR boot server can be defined on a Solaris computer that has a physical IP
presence on multiple networks.
That is, you can use a single Solaris BMR boot server with multiple network interfaces for
Solaris BMR clients on each network segment.
■ Configure a relay boot server to allow Solaris computers on remote subnets to boot from a
BMR boot server using a network gateway. Contact your support representative for a Tech
Note that describes the procedure.

Thanks for responce. what you trying to tell me is excellent but I would like to clarify many things about it but recently i need to know if i prepare one of the physical Solaris machine in side that subnet , so is it will be possible to restore the client to earlier time as one month ago without any problems. the second thing is there are any limitation to register one of the clients to be BMR boot server if this client added to the BMR system as aclient? it will not affect it's main task?

if the Solaris server already added to the BMR system(netbackup 7.5) as client so the bmr software is already preinstalled .Right? what i need is to register then create SRT.

For relay boot server I think i need to read it very well to check if it may solve this issue.

By default BMR will restore a client from it's last backup, but you can point it to a  previous one if you wish.

I thnk a client would be ok as a BMR boot server.  The boot server doesn't do much useless it is booting something, which shouldn't happen that often.

I don't think a client contains the boot server software, you'd have to install this - please check the BMR manual  for this, I've never done this.  However, you are correct, a BMR server just needs to be registered, with the BMR server.

Please see my responses inline,

 

 Q. so is it will be possible to restore the client to earlier time as one month ago without any problems.

JRP... This is possible as long as the client had BMR enabled within the policy at the time of this backup.

 

Q. the second thing is there are any limitation to register one of the clients to be BMR boot server if this client added to the BMR system as aclient? it will not affect it's main task?

 

JRP......If the client is going to be a BootServer, you have to then utilize media boot option if you ever had to recover this host as it will be unavailable to host network boots.

 

Q. if the Solaris server already added to the BMR system(netbackup 7.5) as client so the bmr software is already preinstalled .Right? what i need is to register then create SRT.

 

JRP......The BootServer software is there on your client supported OSs, "bmrsetupboot -register" must be ran so the host assumes the role of a BootServer, no addtl software is required. To create your SRT, you will need the solaris install media, NetBackup client install sw, as well as NetBackup client patch software, the level used to backup your client is suggested.....ie 7.5.0.X.

After you have the required software available to you and have registered the BootServer, you can run bmrsrtadm on the new BootServer/client to begin creating your SRT.
