Re: how to make MIRROR1 on two FC10 DiskSystem?

First of all identify the special files of ur disks
ioscan -kfnCdisk
should be something like /dev/dsk/cXtXdX

build up a LVM structure, let's say u want 1 volume group (VG) with all the disks (PV) in it and 1 logical volume (LV) which will be used as raw device.
The volume group is vg01 (supposed u have only 1 vg, vg00)
the phisical volumes (disks) are /dev/dsk/c1t0d0 and /dev/dsk/c2t0d0, one on each FC10

the commands are:
pvcreate /dev/rdsk/c1t0d0
pvcreate /dev/rdsk/c2t0d0

mkdir/dev/vg01
mknod /dev/vg01/group c 64 0x010000
vgcreate vg01 /dev/dsk/c1t0d0 /dev/dsk/c2t0d0

lvcreate vg03
lvextend -m 1 /dev/vg01/lvol1
lvextend -L /dev/vg01/lvol1

that's it, u can use /dev/vg01/rlvol1 as the raw device for oracle
Note some commands want the raw devices (/dev/rdsk directory) some other the block devices of the disks

See man vgcreate, pvcreate, lvcreate, lvextend for details about the commands

I don't remember if FC10 is a disk array (i think so), in this case first of all u have to configures the LUN on the FC10 and u will have a double raided system: RAID5 or RAID3 on the FC10 and each LV mirrored on the other FC10

Hope this helps
