Looking at FCP-2 Rev 04,
Table 4 - Clearing Effects of SCSI Initiator Actions

Can someone explain the rational for clearing Device Reservations for

For many pieces of FC hardware as of today, this means that Lip(F7)s
will cause Device Reservations to be cleared. I think this
behavior is too drastic in cluster configs; i.e.,  if one host is rebooting
then the other "alive" host's Device Reservation can get effected due to a
Lip(F7). Shouldn't the reboot be as transparent as possible to the "alive"
host ??

Lastly, I realize the Persistent Reservations do NOT behave this way
(but this won't help me here).
