about mirror disk!

system : hp rp5470 os version : 11i
two disk systems :fc10,

now will add two disks into two fc10s

I want to add vg03,considering the security of data ,the two disks make mirror

then add the vg03 into cluster and used at OPS mode!

on host1:

disks:
/dev/dsk/c5t9d0 /dev/dsk/c6t9d0

#midir /dev/vg03
#mknod /dev/vg03/group c 64 0x080000
#vgcreate /dev/vg03 /dev/dsk/c5t9d0
#lvcreate -L 2048 -n data2G00 /dev/vg03
.
.
.
#lvcreate -L 2048 -n data2G10 /dev/vg03


#vgextend /dev/vg03 /dev/dsk/c6t9d0

#lvextend -m 1 /dev/vg03/data2G00 /dev/dsk/c6t9d0
.
.
.
#lvextend -m 1 /dev/vg03/data2G10 /dev/dsk/c6t9d0

#vgexport -s -p -m /tmp/vg03.map /dev/vg03

#rcp /tmp/vg03.map host2:/tmp/vg03.map

on host2

#mkdir /dev/vg03
#mknod /dev/vg03/group c 64 0x080000
#vgimport -s -m /tmp/vg03.map /dev/vg03

is it right ?
Need the parameter quorum be considered?

if needed

how to do it ?

thanks!

Hi

1. your command for vgimport is corect

2. you don't need to consider quorum about the data volumes

Re: about mirror disk!

Did you share those disks between two nodes?

Nowhere you said in your post that those disks are shared. I haven't seen so far cluster disks with mirror. You may try to activate with no quorum option by pulling mirror disk and see if it is able to activate it. Also you want to make it as OPS means read/write on both nodes. you can do it as long as you install software and configure cluster.
