Changing the PLOGI Retry Timer
This option is especially useful for Tachyon-based RAID arrays. Rarely, a
Tachyon-based RAID array resets itself and the port goes offline temporarily. When the
port returns to operation, the PLOGI 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. You can choose:

No PLOGI Retry: 0 msec – default

50 msec takes 5 to 6 seconds per device (if 126 AL_PAs are on the loop)

100 msec takes 12 seconds per device (if 126 AL_PAs are on the loop)

200 msec takes 22 seconds per device (if 126 AL_PAs are on the loop)
To set the interval for the PLOGI retry timer:
1. On the main configuration menu (Figure 6-2), select Configure Advanced Adapter
Parameters and press <Enter>. The adapter configuration menu is displayed
(Figure 6-13).
2. Select Change PLOGI Retry Timer and press <Enter>. Information similar to
Figure 6-15 is displayed.
