Table 11‑3. Additional Parameters for iSCSI Initiators (Continued)
Advanced Parameter Description
DefaultTimeToWait Minimum time in seconds to wait before attempting a logout or an active task reassignment after
an unexpected connection termination or reset.
DefautTimeToRetain Maximum time in seconds, during which reassigning the active task is still possible after a
connection termination or reset.
LoginTimeout Time in seconds the initiator will wait for the login response to finish.
LogoutTimeout Time in seconds initiator will wait to get a response for Logout request PDU.
RecoveryTimeout Specifies the amount of time, in seconds, that can lapse while a session recovery is performed.
If the timeout exceeds its limit, the iSCSI initiator ends the session.
No-Op Interval Specifies the time interval, in seconds, between NOP-Out requests sent from your iSCSI initiator
to an iSCSI target. The NOP-Out requests serve as the ping mechanism to verify that a
connection between the iSCSI initiator and the iSCSI target is active.
No-Op Timeout Specifies the amount of time, in seconds, that can lapse before your host receives a NOP-In
message. The iSCSI target sends the message in response to the NOP-Out request. When the
no-op timeout limit is exceeded, the initiator ends the current session and starts a new one.
ARP Redirect With this parameter enabled, storage systems can move iSCSI traffic dynamically from one port
to another. Storage systems that perform array-based failovers require the ARP parameter.
Delayed ACK With this parameter enabled, storage systems can delay an acknowledgment of received data
packets.
Configure Advanced Parameters for iSCSI
The advanced iSCSI settings control such parameters as header and data digest, ARP redirection,
delayed ACK, and so on.
Caution Do not make any changes to the advanced iSCSI settings unless you are working with the
VMware support team or otherwise have thorough information about the values to provide for the
settings.
Prerequisites
Required privilege: Host.Configuration.Storage Partition Configuration
Procedure
1 Navigate to the host.
2 Click the Configure tab.
3 Under Storage, click Storage Adapters, and select the adapter (vmhba#) to configure.
