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)
Hello,
This morning we have added 6 new disks (73 Gb) to our DS4300, then created a new Array en then created a logical drive, after this was done, teh following error occourd on the last 3 (new)disks:

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,
when I do a failover, hacmp always starts db2 but recently it fails to start db2..noticed the issue is db2nodes.cfg is not modified by hacmp and is still showing primary node..manually changed the node name to secondary after which db2 started immediately..unable to figure out why hacmp is...

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)
I have an array in an external file, "array.txt", which contains:

ifc_disable_mgmt_lun(5) File Formats Manual ifc_disable_mgmt_lun(5)NAME
ifc_disable_mgmt_lun - select whether or not management luns are discovered in the legacy representation of mass storage devices
VALUES
Failsafe
Default
Allowed values
Enable discovery of management luns for array devices.
Disable discovery of management luns for array devices.
Recommended values
DESCRIPTION
Management luns provide the means to access the control ports of Fibre Channel disk arrays. They are represented in both the legacy and
the agile view of storage devices. The legacy representation of a management lun is typically created under a separate virtual extension
bus node. The entry for a legacy management lun looks like this:
On a system with a large number of storage devices connected, creation of management luns can result in an insufficient number of virtual
extension buses for the legacy representation of data luns. Since the number of extension buses on a system is limited to 256, luns
requiring virtual extension buses above 256 will be unusable through legacy device special files. Disabling the discovery and creation of
management luns will free up virtual extension buses for use by data luns.
Who Is Expected to Change This Tunable?
System administrators who expect to use a large number of storage devices requiring more than 256 extension buses through legacy device
special files.
Restrictions on Changing
Changes to this tunable take effect immediately. However, existing management luns will not be removed.
When Should the Tunable Be Turned On?
This tunable should be turned on when the system runs out of extension buses for configuring the legacy representation of data luns.
What Are the Side Effects of Turning the Tunable Off?
None.
When Should the Tunable Be Turned Off?
When the functionality provided by the management luns is desired.
What Are the Side Effects of Turning the Tunable On?
Existing management luns in the legacy representation will show up in the state.
What Other Tunables Should Be Changed at the Same Time?
None.
