in my test machine i can see the filesystem list using bdf commands.
$bdf
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 58916864 6242747 49386840 11% /

I have a scenario where i have to test the sar(1m) command to check the disk activity. for that i need a filesystem which is mirrored and configured with more then one disk.
But unfortunately the above existing filesystems are having only one disk mirrored with it.
# lvdisplay -v /dev/vg00/lvol1
--- Logical volumes ---
LV Name /dev/vg00/lvol1
VG Name /dev/vg00
LV Permission read/write
LV Status available/syncd
Mirror copies 0
Consistency Recovery MWC
Schedule parallel
LV Size (Mbytes) 2000
Current LE 125
Allocated PE 125
Stripes 0
Stripe Size (Kbytes) 0
Bad block off
Allocation strict/contiguous
IO Timeout (Seconds) default
--- Distribution of logical volume ---
PV Name LE on PV PE on PV
/dev/disk/disk4 125 125 <-- Only one disk is mirrored.
Can anyone please let me know, How to add another disk into these existing filesystem? Please help me with the steps for mirroring the disk with filesystem.
Thanks & Regards
