Removing HP MPIO EVA DSM
To remove HP MPIO EVA DSM, you must re-configure the SAN and reboot your system.
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 following steps:
1. Back up all user data on multipath storage.
2. 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 or one-storage array, HP recommends removing redundant cable connections.
• If the storage continues to be accessed by multiple paths, use switch zoning to establish single
path connection.
NOTE:
Ensure you perform steps 1 and 2 before proceeding further.
3. Select Start > Settings > Control Panel > Add or Remove Programs.
4. Select HP MPIO Full Featured DSM for EVA4x00/6x00/8x00 family of Disk Arrays from the
Remove Program drop-down list.
5. Click Remove and follow the on-screen instructions.
The system displays a cautionary statement advising of the potential data loss or corruption that
may result from removing this software.
