IBM System Storage DS3000: Introduction and Implementation Guide
12.The Devices and Properties tabs can be used to get more details about configured LUNs
available to the configured iSCSI sessions. This is useful in case the configuration did not
succeed and the disks do not appear in Device Manager.
13.Figure 18-36 shows the disks as they appear in Device Manager after all connections are
made. The two network interface cards are connected each to two iSCSI ports of the
DS3300. Four logical drives are configured on the DS3300 that are visible over each port.
That makes 16 IBM 1726-3xx FASt SCSI Disk Devices in the Device Manager. Each iSCSI
port of the DS3300 also provides by default the Universal Xport SCSI disk device, whish is
also seen four times. The multipath driver presents 4 IBM 1726-3xx FAStT Multipath Disk
Devices to the host that can be used to create partitions in the next section.

Proceed with the preparation of the shared disks.
18.9 Prepare shared drives on a cluster node
After the software initiator is configured, the logical drives of the DS3300 are available to the
cluster nodes as physical disks. These disks need to be initialized and a partition created and
formatted with an NTFS file system on each. The cluster service requires that the drives are
basic drives, not dynamic drives. We recommend using labels on each disk to identify it by its
drive letter and usage. An example would be
Q_Quorum
for a drive that is mounted as Drive Q:
and used as Quorum Disk resource.
