View Volume Group Information in Tree View
Detailed path information is available in the tree view. From the Storage tab,
select Volume Groups, then the tree view (second icon to the right of Actions).
The tree view shows the following information for each volume group:
■ The list of volume groups, packages (HA systems only), LUNs, and paths
■ The current state of packages, volume groups, and preferred paths. (LUNs do
not have a state.)
— Package states (HA systems only) are Running, Stopped, Failed Over,
Unknown, or Inactive.
If the package is being used by another node, you will see Running (on
<node name>) as the package state. To edit any volume group, LUN, or
path on that package, you must stop the package and make the package
local to your node.
— Volume group states are Active or Inactive
— Preferred path states are Active, Available, Failed, or Unknown
■ Current mode of the paths: Preferred, Alternate, Preferred Off-line, or
Alternate Off-line
■ Path initiator’s (HBA’s) world wide name
■ Path target’s (storage controller’s) world wide name
