Table 10‑5. Additional Parameters for iSCSI Initiators (Continued)
Advanced Parameter Description Configurable On
ARP Redirect Allows storage systems to move iSCSI trac dynamically from one
port to another. ARP is required by storage systems that do array-
based failover.
Software iSCSI
Dependent Hardware
iSCSI
Independent Hardware
iSCSI
Delayed ACK Allows systems to delay acknowledgment of received data packets. Software iSCSI
Dependent Hardware
iSCSI
Configure Advanced Parameters for iSCSI
The advanced iSCSI seings control such parameters as header and data digest, ARP redirection, delayed
ACK, and so on.
C Do not make any changes to the advanced iSCSI seings unless you are working with the
VMware support team or otherwise have thorough information about the values to provide for the seings.
Prerequisites
Required privilege: Host..Storage Partition
Procedure
1 Browse to the host in the vSphere Web Client navigator.
2 Click the Manage tab, and click Storage.
3 Click Storage Adapters, and select the adapter (vmhba#) to congure.
4 Congure advanced parameters.
n
To congure advanced parameters at the adapter level, under Adapter Details, click the Advanced
Options tab and click Edit.
n
Congure advanced parameters at the target level.
a Click the Targets tab and click either Dynamic Discovery or Static Discovery.
b From the list of available targets, select a target to congure and click Advanced Options.
5 Enter any required values for the advanced parameters you want to modify.
iSCSI Session Management
To communicate with each other, iSCSI initiators and targets establish iSCSI sessions. You can review and
manage iSCSI sessions using vSphere CLI.
By default, software iSCSI and dependent hardware iSCSI initiators start one iSCSI session between each
initiator port and each target port. If your iSCSI initiator or target have more than one port, your host can
have multiple sessions established. The default number of sessions for each target equals the number of
ports on the iSCSI adapter times the number of target ports.
Using vSphere CLI, you can display all current sessions to analyze and debug them. To create more paths to
storage systems, you can increase the default number of sessions by duplicating existing sessions between
the iSCSI adapter and target ports.
