|
| usr/es/sbin/cluster/utilities/clrmclstr | be very carefulldelete the cluster completely |
Topology Information |
|
| lslpp -Lqc cluster.es.server.rte | cut -d: -f3 | there is no specific command to get the PowerHa version,but the version of the cluster.es.server.rte refects it. |
| lssrc -ls clstrmgrES \ | egrep "local node vrmf|cluster fix level" |
If you do not trust the above Information, you could ask the cluster manager to display the version |
| cllsnode | list the info about the cluster nodes |
| cllsnode -i NODENAME | list info about node NODENAME |

| cllsnw -n ETHER1 | list the details of network ETHER1 |
| clstat | find the status of cluster |
| clgetif | list interface name/interface device name/netmask associated with a specified ip label / ip address of a specific node |
| cllsparam -n NODENAME | list the runtime parameters for the node NODENAME |
| clgetip RGNAME | get the ip label associated to the resource group RGNAME |
| cllsnim | show info about all network modules |
| cllsnim -n ether | show info about ether network module |
| cllsgrp | list all resource groups |
| cllscf | list cluster topology information |
| cltopinfo | list detailed information about the network of the cluster |
| cldisp | list detailed info about the cluster (not realtime) |
| cldump | list detailed info about the cluster (realtime, shows cluster status) |
Resources |
|
| clfindres | find the status of resource group |
| clshowres | find the properties of a resource group |
| clshowres -g'RG' | show resource information by resource group |
| clshowres -n'NODE' | show resource information by node |
| cllsdisk -g RGNAME | list the PVID of the shared hard disk for resource group RGNAME |
| cllsvg | list the shared vgs which can be accessed by all nodes |
| cllsvg -g RGNAME | ist the shared vgs in resource group RGNAME |
| cllslv | list the shared lvs list the VG of LV |
| cllslv -g RGNAME | list the shared lvs in the resource group RGNAME |

| usr/es/sbin/cluster/utilites/cldare –M RG NODE -N -v | move a Resource Group (RG) to another Node |
Extend a VG in HACMP
configure disks
After running cfgmgr provide the PVID on both the nodes1st Node

Run Discovery on any node
since HACMP need to know the latest changes on the Nodessmitty HACMP-> Extended Configuration->Discover HACMP-related Information from Configured Nodes
This process wil take about 5-10 mins or may be faster
add new disk to Shared Volume Group
Smitty hacmp->System Management (C-SPOC)->HACMP Logical Volume Management->Shared Volume Groups->Set Characteristics of a Shared Volume Group->Add a Volume to a Shared Volume Group
