Pour voir si le disque est HS faire un format --> analyze --> read on the c1t0d0 disk. <br />
<br />
Sinon un metasync peut corriger le problème si le disque n'est pas HS<br />
#metasync d90<br />

== Mettre en miroir deux luns ==<br />
<br />
Partitionner le 2eme disque à l'identique :<br />
prtvtoc /dev/rdsk/c0t0d0s2 | fmthard -s /dev/rdsk/disque2<br />
Création des metadb de sauvegarde (penser à créer la partition)<br />
metadb -fac 3 c0t0d0s7 c0t1d0s7<br />
Editer /etc/lvm/md.tab (fichier de configuration du raid logiciel)<br />
après modif :<br />
metainit -af (initialise le miroir)<br />
metastat (stats du miroir) metaroot d0<br />
<br />
editer le fichier /etc/vfstab pour configurer les autres partitions puis reboot<br />
metattach d0 d2<br />

<br />
Créer et mettre en mirroir des slices:<br />
<br />
Create under c0t0d0s5 four different soft partitions: <br />
d31, d32, d33, d34 as 6GB, 7GB, 4GB and 7GB:<br />
# metainit d31 -p c0t0d0s5 5g<br />
d31: Soft Partition is setup<br><br />
# metainit d32 -p c0t0d0s5 7500m<br />
d32: Soft Partition is setup<br><br />
# metainit d33 -p c0t0d0s5 4400m<br />
d33: Soft Partition is setup<br><br />
# metainit d34 -p c0t0d0s5 7500m<br />
d34: Soft Partition is setup<br><br />
To create a stripe you should create the exact four slices <br />
to the second disk, c0t2d0:<br />
# metainit d41 -p c0t2d0s5 5g<br />
d41: Soft Partition is setup<br><br />
# metainit d42 -p c0t2d0s5 7500m<br />
d42: Soft Partition is setup<br><br />
# metainit d43 -p c0t2d0s5 4400m<br />
d43: Soft Partition is setup<br><br />
# metainit d44 -p c0t2d0s5 7500m<br />
d44: Soft Partition is setup<br><br />
Now we have four soft partitions, or we can consider them as four different slices, <br />
under first disk and another four equal size soft partitions, to the second disk. <br />
We could stripe them and create four mount points to install, Oracle software, for instance.<br />
# metainit d51 1 2 d31 d41<br />
d51: Concat/Stripe is setup<br><br />
# metainit d52 1 2 d32 d42<br />
d52: Concat/Stripe is setup<br><br />
# metainit d53 1 2 d33 d43<br />
d53: Concat/Stripe is setup<br><br />
# metainit d54 1 2 d34 d44<br />
d54: Concat/Stripe is setup<br><br />
Our new volumes are: d51, d52, d53 and d54. These will be our mount points <br />
what we are looking for. We just have to format and add them to the vfstab.<br />
# newfs -v /dev/md/rdsk/d51<br />
# newfs -v /dev/md/rdsk/d52<br />
# newfs -v /dev/md/rdsk/d53<br />
# newfs -v /dev/md/rdsk/d54<br />
<br />
Create the mount points: /u01 /u02 /u03 and /u04 and mount the previous volumes<br />
# mkdir /u01 /u02 /u03 /u04<br />
# mount -F ufs -o logging /dev/md/dsk/d51 /u01<br />
# mount -F ufs -o logging /dev/md/dsk/d52 /u02<br />
# mount -F ufs -o logging /dev/md/dsk/d53 /u03<br />
# mount -F ufs -o logging /dev/md/dsk/d54 /u04<br />
