Setting and Modifying Controller Options
4-4 GAM Client User’s Guide
• Consistency Check Rate . Change the default Rate Controls to less
than or equal to 50. Do this by using the slide bar or typing the rate
in the edit box. A rate of 50 dedicates the maximum allowable
resources to a Consistency Check allowing it to proceed at its
fastest. Lowering the number devotes more resources to I/Os and
consequently slows the Consistency Check process.
• MORE Rate . Change the default Rate Controls to less than or equal
to 50. Do this by using the slide bar or typing the rate in the edit box.
A rate of 50 dedicates the maximum allowable resources to an array
expansion or other MORE operation allowing it to proceed at its
fastest. Lowering the number devotes more resources to I/Os and
consequently slows any MORE process.
•
Auto Drive Sizing
. Allows the software to set similar drive sizes
(e.g. 4.0 GB, 4.1 GB, 4.2 GB) to a common size automatically
without the need to edit the mylexdrv.siz file. This leads to smoother
operation by allowing drives of similar sizes to be treated as
identical sizes for hot spares, replacement drives, and within arrays.
If you disable this option, the software will read and use the current
contents of mylexdrv.siz.
Change some of the following Startup Parameters:
• Disk Spin-up . On Command drive spin-up only.
• Devices Between Spins . Number of devices to spin up at one time.
A low number lessens the likelihood of a power drain.
•
Initial Delay
. Number of seconds between physical device start-ups.
•
Delay Between Spins
. Number of seconds between consecutive
device spin-up cycles.
Clustering . Under Windows XP 32-bit and 64-bit, Windows 2000 or
Windows NT 4.0, allows redundancy among controllers in various servers.
If a controller or server fails, another controller can take over the disk drives
and disk arrays that were formerly handled by the failed controller. This
mechanism imparts a “fault tolerance” among controllers and servers.
Change the following Clustering Parameter:
Controller Host ID
. Change if you want to set this controller’s target ID to
something other than 7.
