ps- I wouldn't ever consider setting it to less than about 15 min, and never
close to 180s as you would be asking for certain trouble.

Subject: [storage-discuss] tcp_keepalive_interval and iscsi
Hi,
Could anyone comment on any recommended TCP tuning specific to the solaris
iscsi initiator? The tcp_keepalive_interval default seems to be 2 hours.
[EMAIL PROTECTED]>]ndd -get /dev/tcp tcp_keepalive_interval
7200000
Assuming that this parameter is in milliseconds then this works out to
7200 seconds. I believe the sd_io_time default is 60 seconds and can be
retried maybe 3 times. If so then does it make sense to have the keepalive
interval longer than 180 seconds? If I have multiple network connections
to the target and mpxio enabled could I reduce path failover time in the
event that I lose a network path be tuning the keepalive interval down to
60 seconds or shorter?
Thanks,
Vic
