Below are the new luns added by the storage team. My cluster setup is a three node HA cluster. I could see the below mentioned luns on all the three nodes :
and we tried to extend the shared volume group through the following steps.
smitty hacmp-->System Management (C-SPOC)-->HACMP Logical Volume Management -->Shared Volume Group-->set Characteristics of a shared volume group-->Add a volume to a shared volume group
We have selected the following shared volume group and resource name.
esbsirg3, sirg3vg1
then selected the new disks..i.e hdisk 26 and hdisk27. After hitting enter, we got the following error..
cl_extendvg: Error executing extendvg sirg3vg1 hdisk27 hdisk26 on node esbsit03
Hello
I am a noobie to HACMP
I have 2 55A servers and a 7031 disk subsystem
For HACMP to work, do I need to have the hdisks on both servers to match the same drives??
The hdisks on each box are currently different:
hdisk0 and hdisk1 are the internal disks and hdisk2-5 are on the D24 on... (1 Reply)
I would like to extend a logical drive on our 3510. I have four unallocated disks which I would like to use for this purpose.
The 3510 supports a Sun Cluster but for now all I wish to see is a "new" disk when I run format.
I am a little familiar with the telnet/ssh session on the 3510 but am... (2 Replies)

Hi,
Can anybody advice whether it is possible to configure HACMP in HP-UX Server.
To my knowledge HACMP is IBM Solution.
Thanks && Regards,

Hi all,
I have an HACMP (v5.3.0.0) cluster vg attached to ibm shark that need to be decommissioned. The data need to move to the HP EVA disk. The OS is on AIX 5200-10. The plan is to add a new disk from EVA & mirror the existing vg & break the mirror from Shark disk once the mirror finished.

Hi,
I have a 2 node Cluster. Which is working in active/passive mode (i.e Node#1 is running and when it goes down the Node#2 takes over)
Now there's this requirement that we need a mount point say /test that should be available in active node #1 and when node #1 goes down and node#2 takes... (6 Replies)
Previous forum threads have noted that AIX cannot use iSCSI disks because it fails when trying to add them to a volume group using mkvg. The failure is caused by AIX's use of the SCSI "WRITE AND VERIFY"(0x2e) command which some iSCSI targets do not support.
We experienced the same problem using... (1 Reply)

cmhaltnode
cmhaltnode(1m)cmhaltnode(1m)NAME
cmhaltnode - halt a node in a high availability cluster
SYNOPSIS
cmhaltnode [-f] [-v] [-t] [node_name...]
DESCRIPTION
cmhaltnode causes a node to halt its cluster daemon and remove itself from the existing cluster.
To halt cluster on the node, a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN allowed in the cluster configu-
ration file. See access policy in cmquerycl.
When cmhaltnode is run on a node, the cluster daemon is halted and, optionally, all packages that were running on that node are moved to
other nodes if possible.
If node_name is not specified, the cluster daemon running on the local node will be halted and removed from the existing cluster.
If you issue this command while a cluster is still in the process of forming, the command will fail with the message "Unable to connect to
daemon." If this happens, wait for the cluster to form successfully, then issue the command again.
Options
cmhaltnode supports the following options:
-f Force the node to halt even if there are packages or group members running on it. The group members on the node will be
terminated. The halt scripts for all packages running on the node will be run; based on priority or dependency relation-
ships, this may affect packages on other nodes. In other words, packages on other nodes may either start or halt based on
this package halting. If the package configuration and current cluster membership permit, and if the package halt script
succeeds, the packages will be started on other nodes. Without this option, if packages are running on the given node,
the command will fail. If a package fails to halt, the node halt will also fail.
-v Verbose output will be displayed.
-t Test only. Provide an assessment of the package placement without affecting the current state of the nodes or packages.
This option validates the node's eligibility with respect to the package dependencies as well as the external dependencies
such as EMS resources, package subnets, and storage before predicting any package placement decisions. If there is a pack-
age in maintenance mode running on the nodes being halted, the package will always be halted and not failover to another
node; the report will not display an assessment for that package.
node_name...
The name of the node(s) to halt.
RETURN VALUE
cmhaltnode returns the following value:
0 Successful completion.
1 Command failed.
EXAMPLES
Halt the cluster daemon on two other nodes:
cmhaltnode node2 node3
