Viewing a List of Concatenated Parity Groups
The storage 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 faster 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 a list of concatenated parity groups:
1. Start LUN Manager and display the LUN Manager window ( Figure 4 on page 21).
2. In the LDEV list, select a logical volume (that is, an LDEV) and then right-click the selected volume.
3. Check to 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
across parity groups.
