How to Configure resource in Sun Cluster.

Yesterday I have created Sun cluster in my test lab environment. I have create it on Solaris 10.

After configuration of cluster I have used below commands to check the status and add the resource into cluster.

Step1 : Instead of running the full command again and again. I added that path.

Checked the status of cluster found the both nodes are in Online status.

export PATH=$PATH:/usr/cluster/bin/

SolNode1:> clnode status

=== Cluster Nodes ===

— Node Status —

Node Name Status
——— ——
SolNode2 Online
SolNode1 Online

Step 2 : As this is newly configured cluster. Quoram is not configured. I have added one shared disk in Oracle Virtual Box which is very easy task. I added that disk in cluster as quoram device.

SolNode1:> clq status

=== Cluster Quorum ===

— Quorum Votes Summary from (latest node reconfiguration) —

Needed Present Possible
—— ——- ——–
1 1 1

— Quorum Votes by Node (current status) —

Node Name Present Possible Status
——— ——- ——– ——
SolNode2 1 1 Online
SolNode1 0 0 Online

Checked the current status of devices which are present in cluster.

SolNode2:> cldev status

=== Cluster DID Devices ===

Device Instance Node Status
————— —- ——
/dev/did/rdsk/d1 SolNode2 Ok

/dev/did/rdsk/d4 SolNode1 Ok

Scanned the new device in cluster to configure it as quoram disk.

SolNode2:> cldev populate
Configuring DID devices

Checked the status using below command whether new disk has been appeared.

SolNode2:> cldev status

=== Cluster DID Devices ===

Device Instance Node Status
————— —- ——
/dev/did/rdsk/d1 SolNode2 Ok

/dev/did/rdsk/d2 SolNode1 Ok
SolNode2 Ok

/dev/did/rdsk/d3 SolNode1 Ok
SolNode2 Ok

/dev/did/rdsk/d4 SolNode1 Ok

 It appears with name of d2 I added that as cluster quoram.

SolNode2:> clquorum add d2

Now check the status of quoram.

SolNode2:> clq status

=== Cluster Quorum ===

— Quorum Votes Summary from (latest node reconfiguration) —

— Quorum Votes by Node (current status) —

——— ——- ——– ——
SolNode2 1 1 Online
SolNode1 0 0 Online

— Quorum Votes by Device (current status) —

Device Name Present Possible Status
———– ——- ——– ——
d2 0 0 Offline

 For me quoram device was showing offline I issued reset command It brought the device in online.

SolNode2:> clq reset
SolNode2:> clq status

=== Cluster Quorum ===

— Quorum Votes Summary from (latest node reconfiguration) —

SolNode1 1 1 Online

Device Name Present Possible Status
———– ——- ——– ——
d2 1 1 Online

Step 3 : Before adding the resource into cluster, We have to register the resource type.

SolNode2:> /usr/cluster/bin/clrt register SUNW.HAStoragePlus

SolNode2:> clrt list
SUNW.LogicalHostname:4
SUNW.SharedAddress:2
SUNW.HAStoragePlus:10

Step 4 : Create one pool named as Sharepool Once again my disk is shared between two nodes.

SolNode2:> zpool create -f SharePool1 /dev/did/dsk/d3s2

SolNode2:> zpool status SharePool1
pool: SharePool1
state: ONLINE
scan: none requested
config:

NAME STATE READ WRITE CKSUM
SharePool1 ONLINE 0 0 0
/dev/did/dsk/d3s2 ONLINE 0 0 0

errors: No known data errors

Step 5 : Create one cluster RG(resource group) and add the resource into group. Here I added the pool as resource in resource group.

SolNode2:> clrg create RG1

SolNode2:> clrs create -g RG1 -t SUNW.HAStoragePlus -p Zpools=SharePool1 CLShare Pool1

SolNode2:> clrs status

=== Cluster Resources ===

Resource Name Node Name State Status Message
————- ——— —– ————–
CLSharePool1 SolNode2 Offline Offline
SolNode1 Offline Offline

Checked the status of resource group it is showing offline.

SolNode2:> clrg status

=== Cluster Resource Groups ===

Group Name Node Name Suspended Status
———- ——— ——— ——
RG1 SolNode2 No Offline
SolNode1 No Offline

Step 6 : We brought the resource group online on one Node.

SolNode2:> clrg online -M -n SolNode2 RG1
SolNode2:> clrs status

=== Cluster Resources ===

Resource Name Node Name State Status Message
————- ——— —– ————–
CLSharePool1 SolNode2 Online Online
SolNode1 Offline Offline

SolNode2:> clrg status

=== Cluster Resource Groups ===

Group Name Node Name Suspended Status
———- ——— ——— ——
RG1 SolNode2 No Online
SolNode1 No Offline

Step 7 : I have migrated the RG1 to another node.

SolNode2:> clrg switch -n SolNode1 RG1

SolNode1:> clrg status

=== Cluster Resource Groups ===

Group Name Node Name Suspended Status
———- ——— ——— ——
RG1 SolNode2 No Offline
SolNode1 No Online

SolNode1:> df -h /SharePool1/
Filesystem size used avail capacity Mounted on
SharePool1 984M 31K 984M 1% /SharePool1
