Hot spare between iSCSI local host adapters

Hot spare between iSCSI local host adapters

The iSeries™ iSCSI local host adapter hardware provides hot spare capabilities to enhance the reliability and recoverability of the Windows server environment. If the iSCSI local host adapter that a Windows server is using fails, you can quickly and easily switch the server to use another "hot spare" iSCSI local host adapter. It also adds flexibility by enabling one "spare" iSCSI local host adapter to be used to protect multiple production iSCSI local host adapters.

Note:

This iSCSI local host adapter hot spare capability complements the hot spare capability that is provided for the integrated server hardware. For more information, Hot spare between server hardware.

To hot spare iSCSI local host adapter hardware using iSeries navigator, do the following steps:

Expand Integrated Server Administration.
Expand iSCSI Connections.
Select Local Host Adapters.
If the network server host adapter (NWSH) for which you want to swap hardware is not already stopped:
- Right-click the NWSH and select Stop.
- Click Stop on the confirmation panel.
- If active servers are currently using the NWSH, a warning message is shown. Click Continue.
To change the NWSH to point to the hot spare iSCSI local host adapter:
- Right-click the NWSH and select Properties.
- Select the General tab and select a new value for the Hardware resource prompt.
- Click OK.
To start the NWSH, right-click the NWSH and select Start.

You can also use the Vary Configuration (VRYCFG) to vary off the NWSH. Then use the Change Device Desccription (NWSH) (CHGDEVNWSH) CL command to change the value for the Resource Name (RSRCNAME) parameter to specify the new hardware resource name.
