IBM Flex System V7000 Storage Node Introduction and Implementation Guide
The lsdev command confirms that the new drives hdisk1 and hdisk2 are FC 2145 (IBM Flex
System V7000 Storage Node volumes) hdisks.
The
mkvg
command can now be used to create a Volume Group with the two newly configured
hdisks. We then use the new hdisks to create filesystems and make them available for users
as shown in Example 12-12.
Example 12-12 Making newly attached storage available for use.
# mkvg -y itsoaixvg1 hdisk1 hdisk2

# mount -t v7kgrp
The lspv command output now shows the new Volume Group label on each of the hdisks that
were included in the Volume Groups. Also, new filesystems are now made available for use as
seen in Example 12-13.
