[SunHELP] Online Backup of a mirrorred root partition

[ymui at royalsunalliance.ca]

Hello Administrators,
Does anyone do online backup of a mirrored root partition (2-way mirror)
using ufsdump for disaster recovery ?
Our environment is Solaris 8 with DiskSuite 4.2.1.  According to the
Disksuite manual, section 'How to use a RAID 1 Volume to make an Online
Backup', the procedure is :
a) lockfs -w (write lock the filesystem).  Do not lock root(/)
b) metaoffline to take one submirror offline from the mirror
c) Unlock the system
d) ufsdump the offlined submirror
e) metaonline to place the offlined submirror back online.
Therefore, this procedure is NOT APPLICABLE to the mirrored root partition.
Very much appreciated to your information.
Best Regards, Y. Mui.
