Four controllers are currently supported.
ΓòÉΓòÉΓòÉ 3. Change/Add Device Option ΓòÉΓòÉΓòÉ
This pull-down option is used to quiet a channel while pulling out or putting
in a SCSI device in a SCSI channel.
ΓòÉΓòÉΓòÉ 4. Get Device Error Option ΓòÉΓòÉΓòÉ
This pull-down option is used to get error counters of configured SCSI devices.
ΓòÉΓòÉΓòÉ 5. Make Standby Option ΓòÉΓòÉΓòÉ
This option is used to assign a Standby status to a replaced device.
ΓòÉΓòÉΓòÉ 6. Rebuild device Option ΓòÉΓòÉΓòÉ

ΓòÉΓòÉΓòÉ 9. SELECT Controller Dialog ΓòÉΓòÉΓòÉ
The "Select Controller" option allows you to select the Controller configured.
This option is grayed if there is only one Controller in the system.
Upto a maximum of 4 Controllers are supported in the system.
ΓòÉΓòÉΓòÉ 10. CHANGE/ADD DEVICE Dialog ΓòÉΓòÉΓòÉ
The "CHANGE/ADD DEVICE" option allows you to quiet a SCSI channel. This option
is used when replacing a dead disk drive by stopping all channel activity on
which the drive is located. Once the drive is replaced, all channel activity
is resumed by starting the channel.
ΓòÉΓòÉΓòÉ 11. HELP ΓòÉΓòÉΓòÉ
1. "SELECT CONTROLLER" option allows you to select the controller configured.
This option is grayed out if there is only one controller in the system. Upto a
maximum of 4 controllers are supported in the system.
2. "GET DEVICE ERROR" option enables you to view the count and types of errors
encountered by each drive.
PARITY ERRORS
This is a count of SCSI bus parity errors that occured while the device was
transferring information on the bus.
SOFT ERRORS
These are 'check condition' errors from the device that indicate a bad sector
was encountered. These errors are recovered by DAC960 Controller.
HARDWARE ERRORS
These errors are generated by one or more of the following conditions:
a) SCSI Processor interrupt for illegal instruction detected.
b) SCSI Processor interrupt for gross error.
c) SCSI device executed an illegal or unsupported phase sequence.
MISCELLANEOUS ERRORS
These errors are generated by one or more of the following conditions:
a) A device timed out on a command issued to it.
b) A device was busy when controller attempted to send it a command.
3. "CHANGE/ADD DEVICE" option allows you to quiet a SCSI channel. This option
is used when replacing a dead disk drive by stopping all channel activity on
which the drive is located. Once the drive is replaced, all channel activity
is resumed by starting the channel.
4. "MAKE STANDBY" option enables you to create a 'Standby' drive as a result
of a dead drive being replaced by a previously configured Standby. The
replacement drive should be identical to the one originally configured. This
option is usable only if the system was preconfigured to have a Standby.
5. "REBUILD DEVICE" option is used for replacing a dead drive on a 'Fault
Tolerant' system drive (ie. RAID 1, RAID 5, RAID 6) when no 'Standby' drive is
present. The controller initiates a rebuild bringing all system drives
dependent on the replaced drive back to consistency. If bad sectors are found
on the system drive, those sectors cannot be rebuilt.
ΓòÉΓòÉΓòÉ 12. GET DEVICE ERROR Dialog ΓòÉΓòÉΓòÉ
The "GET DEVICE ERROR" option enables you to view the number and types of
errors encountered by each drive.
PARITY ERRORS
This is a count of SCSI bus parity errors that occured while the device was
transferring information on the bus.
SOFT ERRORS
These are 'check condition' errors from the device that indicate a bad sector
was encountered. These errors are recovered by DAC960 Controller.
HARDWARE ERRORS
These errors are generated by one or more of the following conditions:
a) SCSI Processor interrupt for illegal instruction detected.
b) SCSI Processor interrupt for gross error.
c) SCSI device executed an illegal or unsupported phase sequence.
MISCELLANEOUS ERRORS
These errors are generated by one or more of the following conditions:
a) A device timed out on a command issued to it.
b) A device was busy when controller attempted to send it a command.
ΓòÉΓòÉΓòÉ 13. MAKE Standby Dialog ΓòÉΓòÉΓòÉ
The "MAKE Standby" option enables you to create a 'Standby' drive as a result
of a dead drive being replaced by a previously configured Standby. The
replacement drive should be identical to the one originally configured. This
option is usable only if the system was preconfigured to have a Standby.
