Viewing a L
ist of Concatenated Parity Groups
The storag
e system 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 f
aster access to data (particularly, faster sequential access to data).
Note
: Only an HP service representative can concatenate parity groups. If you have any questions about
concatenation of parity groups, ask your HP service representative.
You can confirm whether a logical volume is dispersed across two or more parity groups. If the logical
volume is dispersed across parity groups, a dialog box appears and displays a list of the parity groups.
To view alistofconcatenatedparitygroups:
1. Start LUN Manager and display the LUN Manager window (Figure 4 on page 21).
2. In the L
DEV list, select a logical volume (that is, an LDEV) and then right-click the selected volume.
3. Check t
o see if the Concatenation List command appears in the pop-up menu.
•If the Concatenation List command appears, the logical volume is dispersed across parity
groups. Select Concatenation List to view a list of the parity groups (Figure 39 on page 78).
•If the Concatenation List command does not appear, the logical volume is not dispersed
acros
s parity groups.
