NVRAM settings
NOTE:
The HP StorageWorks U320e SCSI Host Bus Adapter is designed to operate properly using factory
settings. Entering invalid or incorrect settings when using an NVRAM configuration utility, such as the
ATTO Configuration Tool, may cause your host adapter to function incorrectly.
CAUTION:
Back up system data before installing or changing hardware configurations.
Use caution when making changes to NVRAM settings and only make changes to those you are familiar
with. Once you have made the desired changes, click one of the following buttons:
• Commit: activates the changes which take effect after rebooting your system.
• Defaults: restores the adapter to factory default settings. The Commit button must be checked
to save any changes.
• Restore: reverts to the NVRAM settings saved the last time the Commit button was used. Clicking
Commit is not necessary.
The upper part of the NVRAM Config panel contains common NVRAM settings that pertain to the entire
channel. The lower part contains settings that can be set for each SCSI ID on the channel.
Controller ID Choices: 0–15
Default: 7
The adapter is normally set to SCSI ID 7 because ID 7 has the highest priority
on the bus. The setting should remain at ID 7 unless you are instructed to
change it by an HP Support representative.
Termination Choices: Auto, High
Default: Auto
Set to Automatic unless there is a narrow SCSI cable connected to the
external connector.
Selection Timeout
(ms)
Choices: 1 ms — 1 sec
Default: 250 ms
Specifies the amount of time a device has to respond to being selected. The
time value can be lowered to speed up the boot process. If the value is
lower than the recommended 250 ms, some devices may not have enough
time to respond.
