Please I would appreciate some inputs on the following:
I have inherited a SUN BLADE chassis with 6 T6320 server modules, in which there is only 1 root disk in all of them. I need to do a backup of the root disk in case those disk crash. But there is no backup device attached to it. So please can I have some ideas how to solve this problem.
If you have no backup devices directly attached the next best is probably to backup to another Solaris box over NFS. So do you have another Solaris box?
Right then. Create a NFS share from the other box and mount it on this one.
Then use
command to snapshot the root filesysytem, and then
command giving the remote NFS as the target for the dump. Job done.
Remember to delete the snapshot afterwards.
(You could script all this stuff.)
If you need to restore after a crash, boot from cd into single user, manually plumb, set ip address and mask, and 'up' the network interface, mount the remote NFS, 'newfs' your local root filesysytem, and ufsrestore the whole thing.
Obviously I don't know your experience level and the above may be too brief. Any questions just ask.
EXTRA NOTE: When you execute 'fssnap' this will output a special device name for the snapshot. This is the device you put in the ufsdump command line (NOT /dev/dsk/c0t0d0s0 or /). This special device reads the frozen snapshot of the filesysytem.
Hi !
I wonder if in solaris 10 there is a utility similar to ignite in HP-UX that backup entire file systems (/, /usr, /var, /tmp, /home).
I have to backup only the root disk of a server, but ufsdump seem to be backing up individual file systems....only, am I correct? (1 Reply)
Hi,
I am trying to use rsync utility through ssh to synchronize some root files of 2 servers.

Hi Gurus out there...
I am pondering over a situation where I have non-root access (user account), where I am trying to determine paths (including multipaths) on a host.
"luxadm display" seems very appropriate, but requires root access.
Is there anyway I can get the FC path information?

We use SW mirroring (RAID1) using SVM for our SUN servers (which we OEM to end clients with our application on). When I need to make a tape backup for the server (disk), I disable mirroring and perform backup of the entire disk to tape using ufsdump. This process requires an outage and sensitive as...
