This topic includes information
about managing your managed disks.
Viewing the MDisk status
You must view the status of managed disks (MDisks) as part
of the repair verification procedures.
Discovering MDisks
You can have the cluster rescan the fibre-channel network.
The rescan discovers any new managed disks (MDisks) that might have
been added to the cluster and rebalances MDisk access across the available
controller device ports.
Adding excluded MDisks to a cluster
You can add managed disks (MDisks) that have been excluded
from the cluster back into the cluster from the Including Managed
Disk panel.
Renaming MDisks
You can rename a managed disk (MDisk) from the Renaming
Managed Disk panel.
Setting quorum disks
You can set a managed disk (MDisk) as a quorum disk from
the Setting a Quorum Disk panel.
Setting the active quorum disk
You can assign one of the quorum disks to
be the active quorum disk in the SAN Volume Controller Console.
In a cluster partition, the active quorum disk is used first to establish
a quorum. Selecting a disk as the active quorum disk is useful in
split-site configurations. Setting the active quorum disk ensures
that the most highly available quorum disk is used in normal processing.
Determining the relationship between MDisks and RAID arrays or LUNs
Each managed disk (MDisk) corresponds with a single RAID
array, or a single partition on a given RAID array. Each RAID controller
defines a LUN number for this disk. The LUN number and controller
name or ID are needed to determine the relationship between MDisks
and RAID arrays or partitions.
