The other button options:
Add:
Used to define the IP addresses of iSCSI target nodes. Enter an IP address for each
additional SCSI Router Instance and click Add. Click Save when you are done adding IP
addresses. A Reboot is necessary for the new configuration to take affect.
Remove:
Used to remove already defined target node IP addresses. Select the IP address to
remove and click Remove. Click Save when you are done removing IP addresses. A Reboot is
necessary for the new configuration to take affect.
Relogin:
Used to cause reconnections to all of the target nodes without requiring a system
reboot. This helps when the SCSI router Instance did not respond properly during login and
the target devices were not seen correctly.
For example, if the access list on the Target is configured incorrectly, there would be no login
response and no indication of what devices would be found. Once the access list is corrected,
this button can be used to reinitiate the login sequences for discovering the correct target
information.
Rescan:
Used to rescan only the SCSI bus represented by the iSCSI driver similar to the
Windows 2000 Disk Management's "Rescan Disks" command.
Target Settings:
(HP 3.1.3 Driver Only) Used to control the usage of iSCSI cyclical
redundancy check (CRC) on the specified target as well as setting the access authentication
username and password.
Global Settings:
(HP 3.1.3 Driver Only ) Used to control the usage of iSCSI cyclical
redundancy check (CRC) on all targets.
Settings:
(HP 3.1.3 Driver Only ) If authentication were ‘enabled’ on the SCSI Router
Instance for this configured connection, you would have to set the access authentication
username and password by highlighting the IP address just created and clicking the Settings
button.
A username and password must be set for each IP Address listed in the main config window
that uses authentication.
Normal/Early Boot
: Use Normal/Early Boot to set the Boot Type to either Early or Normal.
This setting is immediate and does not need a separate Save step.
With Normal Boot configured, the computer may not discover all iSCSI targets before it
completes booting. With Early Boot configured, the computer will discover all available iSCSI
targets before it completes booting.
Because a driver configured for Normal Boot does not log in to the SR2122 until after most of
the Windows 2000 OS has already been initialized, some services and components in the
computer do not activate properly. Two files, actiscsi.vbs (a Visual Basic script file) and
chkiscsi.exe (a utility), are copied onto the system's %SYSTEMROOT%\system32 directory
