Appendix G. Shared storage setup

This chapter gives the details for setting up and configuring the IBM NAS 300
storage.
The following steps need to be followed if your shared storage is not configured,
and only for the first node. If your shared storage is configured, the only steps you
need to do are to create the Quorum disk and ensure that the disks are labeled the
same on each node.
The Model 325 comes with preconfigured shared storage spanning nine disks. The
storage is formatted as an array, at RAID-level 5, consisting of the following LUNs:
v A LUN of 500 MB, for the Quorum drive (drive letter will be G)
v A second LUN, composed of the remaining space (approximately 270 Gbytes)
You can use this preconfigured storage, or delete it and configure new storage. If
you delete it, you will need to complete the steps in this chapter.
Note: If you set up the shared storage with Storage Manager 7, you need to
With Storage Manager 7, you can configure and manage the DASD mounted in the
IBM 5191 RAID Storage Controller Model 2RU (storage controller) and IBM 5192
Network Attached Storage Storage Unit Model 1RU (storage unit) enclosures.
Storage Manager 7 provides a GUI for managing storage subsystems. It features
two main windows:
Enterprise Management
Subsystem Management
You manage the storage subsystems through the Fibre Channel I/O path between
the engines and the RAID controllers (host-agent method). The Storage Manager 7
software is installed on both engines allowing you to manage the storage
subsystems from a Terminal Services session open on either node's engine.

and used as a share drive with one hot spare
configure the storage on one node only. For the other node (the joining
node), the only part of shared storage setup that you will need to complete is
assigning drive letters on the shared storage, making sure that the drive
letters are the same as those on the first node.
Use this window to add, remove, and monitor all
storage subsystems within the management
domain.
Use this window to manage individual storage
subsystem components.
