creating a new shared VG
and adding this to a RG while the cluster is running.
The following steps can be used to create a VG and then add this to a
exsisting RG.
Create VG
smitty hacmp --> System Management --> HACMP Logical Volume
Management --> Shared Volume Groups -->Create a Shared Volume Group
-->select all the nodes --> select new luns/disk --> give new VG
name,set PP size --> press Enter.
Add VG to a RG
smitty hacmp --> Extended Configuration --> Extended Resource
Configuration --> HACMP Extended Resource Group Configuration -->
Change/Show Resources and Attributes for a Resource Group -->
select RG -->In Volume Groups add the new VG--> press Enter.
After performing this action run a sync/verify once and wait for it to
fully complete before doing anything else (check cluster is stable)
I need to get a snap -e from the system and run this through the decoder
just to confirm we don't have any bugs at this level.. But looking on
our database it seems fine.
The process is very straight forward.
1. Create a new VG using the following menu
This creates a enhance capable VG
#smitty cl_admin
HACMP Concurrent Logical Volume Management
HACMP Concurrent Logical Volume Management
HACMP Concurrent Logical Volume Management
Select both nodes using F7 key or participating node
add disk required disks and hit enter
Add new VG to the required Resource group:-
smitty hacmp >> Extended Configuration:-
Extended Resource Configuration
HACMP Extended Resource Group configuration
Change/show attributes
Important:-
Run a sync/verify on the cluster and wait for this to complete and the
cluster to become stable before performing further commands.
check using clstat or cldump command.
/usr/es/sbin/cluster/utilities/cldump
To add LV's and filesystems to this new VG use the HACMP logical Volume
Management menu in the cspoc menu.
