UNIX C/H/S - Some operating system requires the drive geometry for accessing the drive
and it reads the geometry of logical unit by sending MODE SENSE command to the
Galaxy HDi. The drive geometry is specified by number of cylinders(C), number of
heads(H), and the number of sectors per track(S).
Some earlier version of operating system has problem in handling the drive
geometryinformation, and it recognizes the capacity of drive less than actual.
The UNIX C/H/S parameter selects the factors in the following formula by which the Galaxy
HDi calculates the number of cylinders.
(# of cylinders) = (# of sectors in a logical unit) / (# of heads) * (# of sectors per track)
When this is ON, the Galaxy HDi determines the number of cylinders given that the number of heads
is 64 and number of sectors per tract is 256. Otherwise, the Galaxy HDi determines the number of
cylinders given that the number of heads is 16 and number of sectors per tract is 63.
DPO/FUA Bit - The Galaxy HDi writes back the data in its Write Cache when the host
system sends the Synchronize Cache command. Some operating system issues the
Synchronize cache command to the Galaxy HDi only when the DPO(Disable Page Out)/
FUA(Force Unit Access) bit is ON.
Blink On Error - This parameter defines the behavior of the ArryMasStor when a power
supply module or fan module fails. The Galaxy HDi blinks the status LED of all drives
all together when a failure is detected to be visible from the front.
Ignore Stop Unit - This parameter is significant only when the host system connected to
Galaxy HDi is a Mac (Macintosh) OS of Apple computers. For a Mac OS host, this should
be marked to ignore the Stop Unit (RAID subsystem) command processing on the device.
S.M.A.R.T. Monitor - S.M.A.R.T (Self Monitoring Analysis and Reporting Technology) is
a self diagnostics function of Hard Disk Drives. Galaxy HDi can execute S.M.A.R.T. to
each hard disk drive to detect if the drive exceeded the S.M.A.R.T. criteria and the drive
would be killed or warning would be set to be able to make actions before further damage
would be made. “Disabled” means SMART checking is not enabled. “Every Minute”
