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 (
).
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 (
).
•
If the Concatenation List command does not appear, the logical volume is not dispersed
across parity groups.

Deleting LU Paths
CAUTION:
Do not remove LU paths when host I/O is in progress.
To delete LU paths:
1.
Start LUN Manager and display the LUN Manager window (
).
2.
In the tree, double-click a port. The host groups corresponding to the port are displayed.
3.
In the tree, select a host group. The LU Path list displays information about LU paths associated
with the selected host group.
4.
In the LU Path list, select one or more LUNs to which volumes are assigned (if a volume is
assigned to a LUN, the columns on the right of the LUN column are not empty).
5.
Right-click the selection and then select Release LU Path. A message appears asking whether
to delete the specified LU paths.
