4 Downgrading the Enterprise

Virtual Arra y

Support for downgrading from XCS 6.200 depends on the minimum supported versions of your EVA

controller hardware. Due to metadata changes in XCS 6.200, to downgrade it will be necessary

to reinitialize the storage system and restore all data. Before proceeding with a downgrade, you

must contact HP Services to determine if a d owngrade is allowed in your conﬁguration and, if so, to

schedule the procedure.

IMPORTANT :

If you are using a “-B” controller, you cannot downgrade to any version earlier than XCS 6.110. The

HSV200-B and HSV210-B controllers require a minimum version of XCS 6.110.
