The Back-end main category comprises of the DKA pairs, associated MPs, RAID groups, and LDEVs,
where DKA and RAID groups are the main component types that further expand to display the
associated components. Following is the component selection path:
• Back-end > DKA (component type) > Individual DKA pairs > MP (component type) > Individual
MPs.
• Back-end > RG(s) component type) > Individual RAID Groups.
• Individual RAID Groups > Physical LDEVs (component type) > Individual physical LDEVs
• Individual RAID Groups > Pool LDEVs (component type) > Individual LDEVs assigned to a pool
The pool to which the LDEV belongs is also displayed in brackets beside the LDEV ID (for ex-
ample, E:31 [Pool ID:4]).
The number of components associated with a component type is displayed beside it. For example:
• DKA (2)
• RG(s) (6)
In the above image, under Back-end for the XP disk array 10090:
• DKA is a component type. The number (2) indicates the number of DKA pairs available on the
selected XP disk array.
