RE: iSCSI: timers

["Venkat Rangan" <venkat@rhapsodynetworks.com>]

Julo,

I may also be in the minority - these timers are useful to coordinate with
R_A_TOV and E_D_TOV values at the FC end. As an example, R_A_TOV is often
used to reuse Exchange IDs, if there is no activity beyond an R_A_TOV. If
iSCSI doesn't have these timers, there is no guarantees that a gateway can
present to the iSCSI end on how long an inactive task will be held.

On another note, I think there needs to be a timer to allow an inactive
session to be terminated, so a target can reduce the number of open, but
inactive TCP connections at its end.

All timers should be negotiated at login time.
