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)
3.4.2 Creating Shared LVs and File Systems
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,
Options
Description
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.
Options
Description
Mount AUTOMATICALLY at
system restart?
Make sure this field is set to no.
Start Disk Accounting
Make sure this field is set to no.
