After the reboot, check if the server is using the metadevice using df -h

Then create the metadevices for the other side of the mirror and attach them

metainit -f d11 1 1 c0t0d0s0
metainit -f d21 1 1 c0t0d0s1
metainit -f d31 1 1 c0t0d0s3

metattach d30 d31

These disks are PowerPath devices and the only thing diferenciating them are the controllers. One path comes from c3 and the other one comes from c4. After I apply a label on the PowerPath devices, I create a new Solaris Volume Manager metadevice with metainit

root@solaris:/ # metainit d74 1 1 /dev/dsk/emcpower68c
d74: Concat/Stripe is setup

I could specify the metadevice with the options 4 1 disk 1 disk 1 disk 1 disk but I find that if I attach one by one there is less chance of error

root@solaris:/ # metattach d74 /dev/dsk/emcpower69c
d74: component is attached
root@solaris:/ # metattach d74 /dev/dsk/emcpower70c

Creating the mount point for the filesystem

root@solaris:/ # mkdir /mountpoint

Here I’m setting the read and browse properties for the directory to avoid problems if the umask is different than 022

root@solaris:/ # chmod 755 /mountpoint

I mount the filesystem and specify the metadevice

root@solaris:/ # mount /dev/md/dsk/d74 /mountpoint

root@solaris:/ # df -h /mountpoint
Filesystem size used avail capacity Mounted on
/dev/md/dsk/d74 44G 45M 44G 1% /mountpoint

If needed, now with the filesystem mounted you can change the owner and group of this filesystem

root@solaris:/ # ls -ld /mountpoint
drwxr-xr-x 3 root root 512 jul 22 16:19 /nfein

I made this new filesystem for the DBA to hold some files. So I’m changing the owner to oracle and group to dba

root@solaris:/ # chown oracle:dba /mountpoint

root@solaris:/ # ls -ld /mountpoint
drwxr-xr-x 3 oracle dba 512 jul 22 16:19 /nfein
