Air Cleaner User Manual

This screen contains a list of physical volumes on the system and indicates the
volume group to which the physical volume is currently assigned. If a physical
volume is not currently assigned to a volume group, (free) will be indicated in
the volume group column.
Note:
1. Systems that are using IBM Enterprise Storage Server
™
, also known as,
Shark disks, will be displayed in this list during system installation.
However, rebuilding volume groups on to these disks during system
installation will not create “vpaths”. It will recreate the volume group to
the hdisk name. If you would like your volume group recreated using
“vpaths”, specify that the volume group will not be created during
system installation and then recreate it with SysBack once the system is
up and running.
2. Most EMC
®
disk drives will be displayed in this list along with their
“power disk” names.
Note that the Megabytes required field indicates the amount of disk space
required to contain the logical volumes defined for this volume group. The
Currently Selected field contains the amount of disk space selected for the volume
group. These fields are updated to reflect any changes to the logical volumes or as
physical volumes are added or deleted from volume groups.
You cannot select a physical volume assigned to a volume group, other than the
volume group with which you are working. You can add or remove a physical
volume from the currently selected volume group by performing one of the
following:
v To add a physical volume to the selected volume group, highlight any physical
volume marked (free) and press Enter. The name of the selected volume group
is added to the Volume Group column, and the new megabytes of disk space
selected are added to the Currently Selected field.
v To remove a physical volume from the selected volume group, highlight a line
containing the selected volume group name and press Enter. The volume group
