Enclosure serial numbers

The enclosure serial number is used by the Virtual Connect Manager to associate a Virtual Connect domain with a particular enclosure. The enclosure serial number can be altered for maintenance purposes, such as replacement of the enclosure midplane. For more information, see SET ENCLOSURE SERIAL_NUMBER in the HP BladeSystem Onboard Administrator Command Line Interface User Guide on the HP website (http://www.hp.com/go/vc/manuals).

•Enclosure serial numbers are unique as shipped from the factory and must remain unique for proper Virtual Connect Manager operation. Use care when altering the enclosure serial number to ensure that serial numbers are unique within the management network.

•After an enclosure is imported into a domain, do not change the serial number. The enclosure must have the enclosure serial number that was present when imported initially. It cannot be replaced with an enclosure that has a different serial number.

•In the event of an enclosure failure, the replacement enclosure must have the serial number set to that of the failed enclosure before it is placed into the VC domain.

•If you are moving interconnect modules, OA modules, and server blades from one enclosure to another, do the following:

a.Save the VC configuration.b.Move the OAs to the new enclosure.c.Power on the OAs.d.Log in.e.Install the interconnect modules in the enclosure, and then power them up.f.Log in to VCM.g.Restore your configuration.h.Move the server blades to the new enclosure.

If the server blades are already in the new enclosure, the servers are required to be powered off when the VC configuration is restored in the new enclosure.

In an existing VC domain, if the enclosure serial number is changed from the OA with the set enclosure serial-number command, HP recommends that all the VC Ethernet modules be reset through the OA so that the new enclosure number is propagated to all the modules in the enclosure.

CAUTION: Do not attempt to replicate domains within the environment using the save/restore mechanisms. This can create serious errors within the replicated domain and the original domain.

Using multiple enclosures

Multiple enclosure support enables up to four c7000 enclosures to be managed within a single Virtual Connect domain for a total of 128 servers, if double-dense support is enabled while using the Domain Setup
