HP OneView manual Restart interconnect N

Symptom

Unable to remove an enclosure

Possible cause and recommendation

You might be unable to remove an enclosure for the following reasons:

•Lack of communication with the hardware during the remove action can prevent the appliance from being able to properly manage the interconnect, server hardware, and enclosure settings.

To forcibly remove an enclosure from the appliance due to lack of communication, see the UI help for enclosures.

•The enclosure is not removed from the appliance. This is typically a problem on the appliance itself, and the best resolution is to follow instructions in the notification panels.

•The enclosure is removed but due to a communication failure, the configuration requires manual intervention to correct.

If 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 N	(where N is the bay number of a VC interconnect)
	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.

Unable to unconfigure single sign on (SSO) on the Onboard Administrator when adding or removing an enclosure

•The interconnects might still be claimed by the appliance. If this is the case, you have to remove the interconnects manually.

Resolution: Remove all certificates and restart the OA (Onboard Administrator).

1.From the OA user interface, select Users/Authentication.

2.Select HP SSO integration, in the right pane.

3.Verify that Settings, Trust mode is set to Trust by Certificate.

4.Select the Certification Information tab and remove all HP SSO Certificates.

5.Reboot the OA.

6.Re-add the enclosure.
