Answer / mahender reddy
we have 2 ways to configure the root mirroring in veritas
1.use vxdisadm
2.vxencap (encpsulation the disk)
mostly we are using the vxencap because vxdiskadm is the
lenthy process
===================
PROCEDURE
===================
1.take the onther disk egual size of root disk
2.for example the 2 disks c1t0d0(root disk) and c1t2d0
3.encaplating the root disk
vxencap -c -f -g <diskgroupname> sliced d0=c1t0d0
4.reboot the server
reboot the server only modify the disk in vfstab and in
etcsysem
5.take the second disk under control of veritas
vxdisksetup -i c1t2do
vxdg -g <diskgroupname> adddisk c1t2d0
6.add the mirror disk to root disk
vxmirror -g <diskgroup name> c1t0d0 c1t2d0

Hello Everyone, One of our servers is showing a strange issue, let me paste the output Code: root # uptime 4:37pm 3 users, load average: 0.00, 0.04, 0.04 Its been running since months but you can see after time there isn't any output like up 191 days(s). Even the who command with b and r option isn't giving any output. Code: root # who -b root # root # who -r root # the date command displays correct output. I am not sure but is it because someone has played with utmpx and wtmpx files, is reboot the only solution we have. Can anyone help us since we don't intend to reboot the server for such a reason and also no one has complained till yet.
