Re: Suns-at-Home digest, Vol 1 #622 - 7 msgs

Here is a how-to I put together quite a while ago. Since "ufsdump" was 
(aparently) "dump" back in 4.1.3 days you should probably check the man 
page to see if the options were the same. Obviously the disk devices I 
list below are Solaris. I know I have also used ufsdump to copy a file 
system from one partition to another as well. The man page describes the 
fairly well under Solaris. I prefer ufsdump over dd since you do not 
have to worry about maintaining the same partition or disk size. The key 
thing you need on the restore is to restore the boot block using 
installboot (not sure if this is Solaris only or not). Here it is:

Replacement of a hard drive (Solaris 2.6):

1. make a backup of the drive to be replaced using the ufsdump command
to make the backup to tape. Ex: Replace system drive c0t3d0 for sparc
systems (and c0t0d0 for ultra and ss1000) assuming the tape is located
at /dev/rmt/0

# df |grep /dev/dsk/c0t3d0 |cut -d' ' -f1
# /usr/sbin/ufsdump 0uf /dev/rmt/0n /
# /usr/sbin/ufsdump 0uf /dev/rmt/0n /usr
# /usr/sbin/ufsdump 0uf /dev/rmt/0n /var
# /usr/sbin/ufsdump 0uf /dev/rmt/0 /opt

2. Add the new drive on an unused SCSI location, ID 2 for example. Then
do a reconfiguration boot.

3. format the NEW drive now at location 2

4. newfs all the new partitions to create the new file systems

5. If the drive is to be a system drive you MUST  install the boot block
with the following command:

# /usr/sbin/installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk 
/dev/rdsk/c0t2d0s0

6. Create a location to mount the new drive partitions and restore the
data from tape. Be carefull about what partition was created on the tape in
what order so as not to restore the wrong partition in the wrong place.

# mkdir /mnt
# mount /dev/dsk/c0t2d0s0 /mnt
# cd /mnt
# ufsrestore rvf /dev/rmt/0n

Repeat on all the partitions to be added to the new drive. Since this was
the root partition, all of the secondary partition directories will have
been recreated. Therefore it will not be necessary to mkdir these
directories.
