Removal Procedures - Oracle RAC Environment

To remove HDLM:

1. Log on to Windows as a member of the Administrators group.

2. Stop the Oracle RAC instance of the host where HDLM is to be removed.

3. If a host and a storage system are connected via multiple paths,

reconfigure it so that only one path connects the host to the storage

system.

Removing HDLM in a multi-path configuration, might cause the disk

contents to become corrupted when the host restarts. Make sure that you

remove HDLM in a single path configuration only.

Figure 3-7 Single Path Configuration and Multi-path Configuration on page

3-89 shows a single path configuration and a multi-path configuration.

4. From Control Panel, choose MPIO.

The MPIO Properties dialog box opens.

5. On the MPIO-ed Devices page, select the hardware ID, and then click

the Delete button.

For an EMC CX series:
