If the Enclosure Does Not Initialize
It may take up to two minutes for the enclosures to initialize. If the enclosure does
not initialize:
■ Perform a rescan.
■ Power cycle the system.
■ Make sure the power cord is properly connected and check the power source that
it is connected to.
■ Check the event log for errors.
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:
1. Select Manage > General Config > Enclosure Management > Reorder Enclosure
IDs.
2. In the Reorder Enclosure IDs panel, click Rescan.
