IBM Certification Study Guide  AIX HACMP

Use the 

smit mkvg 

fastpath to create a shared volume group. Use the default 

field values unless your site has other requirements, or unless you are 
specifically instructed otherwise.

Table 15.  smit mkvg Options (Concurrent, RAID)

Use the 

smit crjfs

 fast path to create the shared file system on the source 

node. When you create a journaled file system, AIX creates the 
corresponding logical volume. Therefore, you do not need to define a logical 
volume. You do, however, need to later rename both the logical volume and 
the log logical volume for the file system and volume group.

Table 16.  smit crjfs Options

Renaming a jfslog and Logical Volumes on the Source Node
AIX assigns a logical volume name to each logical volume it creates. 
Examples of logical volume names are

 /dev/lv00 

and 

/dev/lv01

. Within an 

HACMP cluster, the name of any shared logical volume must be unique. Also, 

VOLUME GROUP name

The name of the shared volume group should be
unique within the cluster.

Activate volume group
AUTOMATICALLY at system
restart?

Set to no so that the volume group can be
activated as appropriate by the cluster event
scripts.

ACTIVATE volume group after it
is created?

Set to yes.

Volume Group MAJOR
NUMBER

While it is only really required when you are using
NFS, it is always good practice in an HACMP
cluster to have a shared volume group have the
same major number on all the nodes that serve it.
Use the 

lvlstmajor

 command on each node to

determine a free major number common to all
nodes.

Create VG concurrent capable?

Set this field to no. 

Mount AUTOMATICALLY at
system restart?

Make sure this field is set to no. 

Start Disk Accounting

Make sure this field is set to no.
