HP MSA Controllers - Manual (Page 38)

iSCSI host ports should be assigned IP addresses that are on one or the other subnet
to which data host ports are assigned. That is, one iSCSI host port on controller A
should be on the same subnet as one of the data host ports, with the other iSCSI host
port on the subnet as the other data host port, and likewise for controller B.
Correcting Enclosure IDs
When installing a system with drive enclosures attached, the enclosure IDs might
not agree with the physical cabling order. This is because the controller might have
been previously attached to some of the same enclosures and it attempts to preserve
the previous enclosure IDs if possible. To correct this condition, make sure that both
controllers are up and perform a rescan using SMU or the CLI. This will reorder the
enclosures, but can take up to two minutes for the enclosure IDs to be corrected.
To perform a rescan using the CLI, type the following command:
To rescan using SMU, as an Advanced Manage user:
1. Select Manage > Utilities > Disk Drive Utilities > Rescan.
2. In the Rescan For Devices panel, click Rescan.
Next Steps
Now you are ready to connect the data and management hosts, as described in
Chapter 3.
