Viewing a list of concatenated parity groups
The XP10000/XP12000 supports concatenation of parity groups. If parity groups are concatenated, a
logical volume can be dispersed across the concatenated parity groups. Dispersal of logical volumes can
provide faster access to data (particularly, faster sequential access to data).
1. Start LUN Manager, and display the LUN Manager pane ( Figure 7 ).
2. In the LDEV table, right-click a logical volume (an LDEV).
If the parity groups are concatenated, the Concatenation List command is available in the shortcut
menu.

4. Click OK to return to the LUN Manager main pane.
