volumes, the RAID group information of the external storage volume is displayed as Ext-RdGp. All
volumes of the external array group is considered as a single non-existing (virtual) group, is termed
as the External RAID Group and is denoted by Ext-RdGp. Performance data is collected for all the
volumes.
All virtual volumes that are not associated with any pool, do not have RAID group information, and
of unknown type, are considered as a single non-existing (virtual) volume group. This single non-existing
(virtual) volume group is denoted as VVol-Grp in the RAID Grp column in the LDEV table and
Performance data is collected for all these volumes.
Viewing SLPR information
Click a SLPR value in the LDEV table to view the detail view for that SLPR in a separate browser
window. In the SLPR window, the line above the table indicates the hierarchical information of the
selected SLPR. The SLPR view includes two tabs, the CLPR tab and the Ports tab.
The CLPR tab displays the following details for each CLPR belonging to the selected SLPR:
