Setting The Mode For The Kgpsa-Xx Host Adapter; Example Of The Set Mode Diag Command And The Wwidmgr -Show Adapter Command; Example Results Of The Wwidmgr Command - IBM TotalStorage DS6000 Attachment Manual

Figure 8. Example of the set mode diag command and the wwidmgr -show adapter command
Figure 8 shows the worldwide node name (WWNN). You need the worldwide port
name (WWPN) to configure the storage unit host attachment. To determine the
WWPN for the KGPSA adapters, replace the "2" in the WWNN with a "1".

Setting the mode for the KGPSA-xx host adapter

This task describes setting the mode for the KGPSA-xx host adapter.
You must install the KGPSA-xx host adapter before you can set the mode.
The default KGPSA mode setting is FABRIC, so directly attaching the AlphaServer
to the storage unit using fibre-channel KGPSA-xx adapters does not work without
modification. You must change the mode setting to LOOP mode.
1. Type # shutdown -h now to shutdown the operating system.
2. Type init to initialize the system.
3. Type wwidmgr -show adapter to check the mode. Figure 9 shows example
