22 LUN Manager for the XP10000/XP12000
When you select a Fibre Channel port in the LU Path tree, the WWN table appears in the lower-left corner
of the LUN Manager pane. The WWN table lists host bus adapters that are connected to Fibre Channel
ports on the disk array.
The table contains the following information:
• A list of ports
• Host Group: Host groups are used to classify servers (hosts) connected to the disk array. You can create
host groups in the LUN Manager pane.
• Name: Indicates nicknames for hosts. Nicknames can be specified in the LUN Manager pane.
• WWN: Each worldwide name represents one host.
LDEV table
The LDEV table in the lower-left corner of the LUN Manager tab lists LDEVs in the disk array. The LDEV
table does not list Auto LUN-reserved LDEVs.
The table contains the following information:
• A list of CU images
• LDEV: A combination of the CU image number and LDEV number that identifies an LDEV. If an LDEV
number ends with #, the logical volume is an external LU. If an LDEV number ends with V, the logical
volume is a virtual volume.
The following icons indicate LDEV status:
• Emulation: Emulation type for each LDEV
• Capacity: Size of each LDEV
• RAID: RAID level for each LDEV. If the logical volume is an external LU or a virtual volume, the RAID
column displays a hyphen (-) instead of a RAID level.
• Parity Group: Displays names of parity groups. If a parity group name begins with E, the parity group
consists of one or more external LUs. If a group name begins with V, the group is a V-VOL group
consisting of one or more virtual volumes.
• Paths: The number of alternate paths, if any
• VMA:Access Attribute: Access attribute of each logical volume. If a VMA is set on a logical volume,
VMA: appears at the beginning of the access attribute.
Buttons

• Cancel: Cancels settings in the pane
