Private Host Drive Belonging To Another Intel RAID Controller SRCMR
This is a host drive on a clustering I/O channel. This host drive is configured as a private host drive
and does not belong to the selected Intel RAID Controller SRCMR. A private host drive cannot be
used for clustering.
Clustering means that two or more servers share resources. If one server fails its resources move to
another valid server. The hard disks used for clustering are physically not connected with just one
Intel RAID Controller SRCMR, but with several Intel RAID Controller SRCMRs in different
servers (shared I/O channels). Usually, when booting a cluster, the Intel RAID Controller SRCMR
starting up first will gain control over all host drives on the clustering I/O channels. If you want to
be sure that a host drive is controlled by a specific server, you may configure this host drive as a
private host drive. A private host drive cannot be used for clustering.

NOTE
You cannot change the configuration of a private host drive which does not belong to the array of
the selected Intel RAID Controller SRCMR. You must use StorCon to change its configuration. A
private host drive belonging to the selected Intel RAID Controller SRCMR is displayed like a
normal host drive.
