Disk Assignments - IBM System Storage N3700 Hardware And Service Manual

Disk assignments

In the N3700 storage system, each node must have ownership of at least one SES
disk in each disk shelf in the system. For example, in a single disk shelf system,
Node A could own the disk in bay 0, and Node B would then own the disk in bay 1.
In a factory-configured system, one node has ownership of one SES bay disk and
the other node owns the second SES bay disk. In addition, each node has
ownership of one parity disk and one spare disk. Node B owns disks 0b.16, 0b.18,
and 0b.20, and Node A owns disks 0b.17, 0b.19, and 0b.21. The balance of the
disks are unowned.
If you add storage to your N3700 storage system, it arrives with unowned disks.
You must assign ownership of the SES disks to the appropriate node.
Notes:
1. Always install the hard disk drives sequentially in adjacent drive bays in the
2. You can change the disk ownership pattern after initial setup. For information
Figure 3 on page 13 identifies the SES bays in the N3700 storage system or in an
expansion unit disk shelf.
Note: N3700 systems with the load board feature must contain no Fibre Channel
