VCS Configruation: Part I

The below post will show how to create a Cluster HA filesystem resource:

[root@node1 /]# vxdisk -e list
DEVICE       TYPE           DISK        GROUP        STATUS               OS_NATIVE_NAME   ATTR
disk_8       auto:cdsdisk   -            -           online               sdc              -
sda          auto:none      -            -           online invalid       sda              -
sdb          auto:LVM       -            -           LVM                  sdb              -
[root@node1 /]#

[root@node2 ~]# vxdisk -e list
DEVICE       TYPE           DISK        GROUP        STATUS               OS_NATIVE_NAME   ATTR
disk_8       auto:cdsdisk   -            -           online               sdb              -
sda          auto:none      -            -           online invalid       sda              -
[root@node2 ~]#


Creating a disk group:

[root@node1 /]# vxdg init oracle disk_8
[root@node1 /]# vxdg list
NAME         STATE           ID
oracle       enabled,cds          1394886552.14.node1.cluster.com
[root@node1 /]#

Creating a volume:

[root@node1 /]# vxassist -g oracle make oracle_vol 500M
[root@node1 /]# vxprint -g oracle
TY NAME         ASSOC        KSTATE   LENGTH   PLOFFS   STATE    TUTIL0  PUTIL0
dg oracle       oracle       -        -        -        -        -       -

dm disk_8       disk_8       -        2027264  -        -        -       -

v  oracle_vol   fsgen        ENABLED  1024000  -        ACTIVE   -       -
pl oracle_vol-01 oracle_vol  ENABLED  1024000  -        ACTIVE   -       -
sd disk_8-01    oracle_vol-01 ENABLED 1024000  0        -        -       -
[root@node1 /]#

Formating and Mount the filesystem:

[root@node1 /]# mount -t vxfs /dev/vx/dsk/oracle/oracle_vol /oracle
[root@node1 /]# df -Th /oracle
Filesystem    Type    Size  Used Avail Use% Mounted on
/dev/vx/dsk/oracle/oracle_vol
              vxfs    500M  3.3M  466M   1% /oracle
[root@node1 /]#
