HP MPIO Full Featured DSM for P6x00 family of Disk Arrays 4.04.00 Installation and Reference Guide (757324-001, May 2014)

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 > Control Panel > Programs > Programs and Features.
4. Select HP MPIO Full Featured DSM for P6x00 family of Disk Arrays from the Program drop-down
list.
5. Click Uninstall 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.
6. Close the Programs and Features window.
NOTE: The LUNs may be inaccessible at this time.
7. Reboot the system.
Using silent installation
