27.5 Troubleshooting enclosures and enclosures groups

27.5.1 Add or remove enclosure is unsuccessful

Symptom Possible cause and recommendation

Unable to add an If the enclosure add fails, a notification panel provides the reason the add action failed and

enclosureprovides a solution to the problem. Often, the resolution is to click the add link that is embedded in the message; the add action rediscovers all components and updates its knowledge of the enclosure.

Enclosure is already being managed by some other management software and is claimed by that software

1.If a first-time enclosure add fails, verify that the enclosures prerequisites listed in add an enclosure to manage its contents are met. Verify that the data you entered on the screen is corrects, and try the action again.

2.Follow the guidance in the notification panel for the corrective action you need to take to successfully add the enclosure.

Failures can occur during the add action if all information about an enclosure, its server blades, or interconnect modules cannot be acquired. When this happens, an explanation of the problem and the component that caused the problem (the enclosure, a server blade, an interconnect) is provided in a notification panel.

3.To re-add an enclosure, click the add link in the notification message panel (if there is one), or start the add action again from the Add Enclosure screen, supplying the address and credentials for the enclosure's Onboard Administrator.

To forcibly add the enclosure to the appliance, see the UI help for enclosures.

Unable to forcibly add You forcibly added an enclosure but received an error message. This happens only in some

an enclosure	cases where there is a VCMode set and virtual connect is managing the enclosure.
	1. Manual clean-up of the configuration is needed, investigate the following items:
	• The management URL might still point to the appliance. If so, it needs to be reset to point
	at the first interconnect in the enclosure. To fix this, use the following ssh commands to
	go into the Onboard Administrator (using administrator credentials) and change the
	management URL to point to the first active VC interconnect's IP address:
	clear vcmode	Disassociates the enclosures from the appliance.
	restart interconnect	(where N is the bay number of a VC interconnect)
	N	Preforming this step for every VC interconnect in the
		enclosure causes the interconnect to revert to a default
		configuration.
	restart oa N	(where N is the bay number of the active Onboard
		Administrator) This causes the OA to obtain the
		management URL from the first VC interconnect.

An existing enclosure is detected as being new after a midplane is replaced

2.After manual configuration, Re-add an enclosure or refresh the enclosure.

You replaced the enclosure midplane but did not follow the recommended procedure in the hardware documentation.

Recommendation: Re-add an enclosure
