Removing HP MPI

OEVADSM

To remove the HP

MPIO EVA DSM, you must re-conﬁgure the SAN and reboot your server.

CAUTION:

Removing multipathing software from a multipath ha rdware 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:

1. Back up all user data on multipath storage.

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

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

use the following guidelines:

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

connections.

• If the storage continues to be ac cessed 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.
