mklv -y'lv03' -c'2' appsvg 64 hdisk1 hdisk2

now this would define that you are useing 64 physical partitions for this Logical Volume.

to me that says

you use 64 on hdiskd and 64 on hdisk2(the mirror disk) is this correct? or am i not understanding this properly.


hdisk1 and hdisk2 are both part of appsvg.

can someone explaine it to me or point me in the right direction?

My understanding is the '64' in your case defines the total number of logical partitions across all drives, not per drive. Note this is different then physical paritions (PP) which refers to disks. In your example you would have 2 PPs (hdisk1 and hdisk2) and 64 total LPs. I do not know if this means you will have 32 LPs per disk or how the OS splits it up. After you run your mklv, if you do an lslv you should see the PP and LP values of 64 and 2 respectively I believe.

With this command you will create logical volume with name lv03 to appsvg volume group having two copies (mirroring) in hdisk1 and hdisk2 with size 64 logical partitions.

Because you have two copies about your logical partitions it makes 128 physical partions totally, having 64 in both physical disks.

With command lslv -m <lvname> you could find out information how your logical volume is mirrored.

after i played around with it i think i was just being retarted and not opening my eyes.
