ncrs(7D) Devices SunOS 5.5

each of the targets starting with target 0. The following values are

accepted: 10.0, 10, 6.67, 6.66, 5.0, 5, 4.0, 4, 3.33, 3.3, and 0. If any

other value is speciﬁed or if 0 is speciﬁed for a target, the adapter

will operate in Asynchronous I/O mode for that particular target.

For example, the entry max-sync-rate="10,10,10,10,10,10,10"

speciﬁes a maximum synchronousI/O rate of 10 for all targets.

This is the default.

no-disconnect The disable disconnections property controls the disconnection

option for each target on theSCSI bus. By default the adapter

allows a target to disconnect at any time. If the no-disconnect pro-

perty is speciﬁed, the adapter will not allow the target devices

listed to disconnect. Each of the comma separated values speciﬁes

a target device for which the option will be disabled. The valid tar-

get ids are 0 through 7.

For example, the entry no-disconnect=4,6 disables the disconnect

option for target devices 4 and 6.
