Change the PLOGI Retry Timer
This option is especially useful for Tachyon-based RAID arrays. In rare situations, a
Tachyon-based RAID array may reset itself and the port may go offline temporarily.
When the port returns to operation, the PLOGI (port log in) retry interval scans the loop
to discover this device. The PLOGI retry interval is the time it takes for one PLOGI to
scan the whole loop (if 126 ALPAs are on the loop). You can choose:

No PLOGI Retry: 0 msec – default

50 msec takes 5 to 6 seconds per device.

100 msec takes 12 seconds per device.

200 msec takes 22 seconds per device.
To set the interval for the PLOGI retry timer:
1. On the main configuration menu (Figure 4-2), select Configure Advanced Adapter
Parameters. The adapter configuration menu is displayed (Figure 4-9).
2. Select Change PLOGI Retry Timer. Information similar to Figure 4-11 is displayed.
