Deleting unneeded WWNs from the WWN name table
If you disconnect a host that was connected via a cable to the array, the host's WWN remains in the
WWN name table on the LUN Manager pane.
1.
Start LUN Manager. The LUN Manager pane (
) appears.
2.
In the WWN name table, locate WWNs that are not registered in any host group. (If the Host Group
column is blank, the WWN is not registered in any host group.) From these WWNs, right-click the
WWN you want to delete, and select Erase WWN.
3.
Click Apply. A confirmation message appears.
4.
Click OK. Settings are applied to the array.
Deleting (initializing) unneeded iSCSI names
If you disconnect a host that was connected via a cable to the array, the host's iSCSI name remains in
the iSCSI name list on the LUN Manager pane.
1.
Start LUN Manager. The LUN Manager pane (
) appears.
2.
In the LU Path tree, right-click the iSCSI folder, and select Initialize iSCSI name.
NOTE:
If there are no unneeded iSCSI names, the shortcut menu does not appear.
3.
Click Apply. A confirmation message appears.
4.
Click OK. Settings are applied to the array.
Viewing a list of concatenated parity groups
The array 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 HP maintenance personnel can concatenate parity groups. If you have questions about
concatenation of parity groups, contact you HP account support 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 pane appears and displays a list of the parity groups.
1.
Start LUN Manager. The LUN Manager pane (
) appears.
2.
In the LDEV table, right-click a logical volume (that is, an LDEV).
3.
Check to see if Concatenation List appears in the shortcut menu.
• If Concatenation List appears, the logical volume is dispersed across parity groups. Select
Concatenation List to view a list of the parity groups.
