If the ETERNUS disk array device and Fibre Channel switch icons are dropped onto the Performance Management window, the logical configuration tree of the device can be displayed as shown below.
"AffinityGroup" indicates a number of the zone function of the selected storage system.
"LUN" indicates a logical unit number from the point of view of the server node. Since this is allocated with Logical Volume (OLU and LUN_V) that specifies a number unique to a device managed in the device, this is expressed as "LUN X(Logical Volume X)" in the tree.
"RAID Group" located under "LUN" indicates that LUN is included in "RAID Group" (rank). [Disk](=physical drive) under [RAIDGroup] or [RAIDGroup [X- X]] indicates the drive used to configure the rank. [LogicalVolume] under [RAIDGroup] or [RAIDGroup [X- X]] indicates the numbers of other LogicalVolumes that belong to the same RAIDGroup. [RAIDGroup X- X] also has devices that are not shown.
[fc X/Y] and [port Y] are the Fibre Channel switch ports. X is "Slot Number", and Y is "Port Number".
X and Y are hexadecimal numbers that start with "0x". Other numbers are decimal numbers.
Place the mouse cursor on the device name on the tree to display the properties as tool tips.
