After you click Request Data, the system retrieves the requested data and displays the results of your query
in the Grid Display screen.
To view the details of the Grid Display query screen components, see
Table 10 .
You can have 16384 logical devices (LDEVs) per array in a XP12000 and XP10000. To increase the
number of LDEVs use, Global Logical Partition (GLPR). You can have four GLPRs per array, each GLPR
has 64 control units (CUs), and each CU has 256 LDEVs, making a total of 16384 LDEVs per GLPR.
Hence, the total numbers of LDEVs for an array, using GLPR is 65279.
NOTE:
GLPR is applicable only for XP10000, XP12000,SVS200, and XP24000 arrays. You can create GLPRs
only in a mainframe environment.
The relationship between GLPR, CU, and LDEV for XP12000, XP10000 and XP24000 is explained
in Table 2 .
Table 2 Relationship between GLPR, CUs and LDEVs
GLPR ID CU LDEV
GLPR #0 0 - 63 0 - 16383
GLPR #1 64 - 127 16384 - 32767
GLPR #2 128 - 191 32768 - 49151
GLPR #3 192 - 254 49152 - 65279
Using the Grid Display screen
Depending on the items selected in the Grid Display query screen, the system retrieves the requested data
and displays the results in a scrolling list box in the Grid Display screen, as shown in Grid Display screen .

For a list of the Grid Display screen components, see Table 11 .
If you do not see Total I/O, Total MB/s, and Total Track fields, it is because you have the external RAID
group, RAID group, XP Thin Provisioning and Snapshot pool information components split between two
data configuration schedules.
