CAUTION:

Removing multipathing software from a multipath hardware conﬁguration can cause data loss or

corruption. You must disconnect the server from the multipath storage or eliminate all but one path to

that storage from the server prior to removing the HP MPIO EVA DSM.

To remove HP MPIO EVA DSM, complete the steps below:

Back up all user data on multipath storage.

If possible, disconnect the storage from the server. If it is necessary to maintain single-path

connections from the server to the storage (as in the case of servers that boot from a SAN device),

use the following guidelines:

• If it is a one-host/one-storage array, HP recommends removing redundant cable connections.

• If the storage continues to be accessed by other servers still in multipath mode and by this

server in single-path mode and it is on an EVA system, use switch zoning to establish the

single connection (path) from the server.

NOTE:

Make sure you perform step 1 and step 2 before proceeding further.

Select Start > Settings > Control Panel > Add or Remove Programs.
