SC. add mount point to oracle HA cluster

1) add zone in fabric
2) add disk mapping in your storage
2.1) rescan scsi on server
# cfgadm -al
3) disk must be viasible in 4 ways, 2 path in each fabric (best practice)
# mpathadm list lu
        /dev/rdsk/c8t60060E80056213000000621300000030d0s2
                Total Path Count: 4
                Operational Path Count: 4

4) update did devices
# scdidadm -r
# scdidadm -u
# scdidadm -i

check did device  on both nodes
# scdidadm -L | grep 21300000130d0
24       node-n2:/dev/rdsk/c8t60060E80056213000000621300000130d0 /dev/did/rdsk/d24    
24       node-n1:/dev/rdsk/c8t60060E80056213000000621300000130d0 /dev/did/rdsk/d24    

5) label disk using format command

6) add disk to nesosary diskset
# metaset -s oracle-disk -a /dev/did/rdsk/d74

7) create metadevice
# metainit -s oracle-disk d81 1 1 /dev/did/rdsk/d74s0
oracle-disk/d81: Concat/Stripe is setup
# metainit -s oracle-disk d80 -m d81
oracle-disk/d80: Mirror is setup

8) create fs 
newfs /dev/md/oracle-disk/rdsk/d80

9) add entry to /etc/vfstab, try manualy mount disk to directory (on both node)

10) get current cluster configuration for disk resource
[root@KGBI-SRV003-n1:/export/apenner]# scha_resource_get -O extension -R oralce-disk -G oracle FileSystemMountPoints

STRINGARRAY
/oracle/u01
/oracle/u02
/oracle/u03
/oracle/u04
/oracle/u05
/oracle/u06
/oracle/u07

11) modefy resource
scrgadm -c -j oracle-disk -x FileSystemMountPoints="/oracle/u01,/oracle/u02,/oracle/u03,/oracle/u04,/oracle/u05,/oracle/u06,/oracle/u07,/oracle/u08"
