Arguments
Description
– RAID 5: 100 MB
– RAID 10: 100 MB
NOTE: If this option is not provided,
RAIDCFG determines the maximum
possible virtual disk size and creates it.
-wp or
writepolicy
wb, wt, wc, nwc
Sets the write policy for the virtual disk. The
valid arguments are:
• wb — Write-Back caching sets the
controller to send a write-request
completion signal as soon as the data is in
the controller cache but has not yet been
written to disk.
• wt — Write-Through caching sets the
controller to send a write-request
completion signal only after the data is
written to the disk.
NOTE: The wb and wt options are
supported on the following RAID
controllers only:
• PERC 5/E Adapter, PERC 5/I
Integrated, PERC 5/i Adapter
• PERC 6/i Integrated, PERC 6/i
Adapter, PERC 6/E Adapter
• PERC 7 and PERC 8
• wc — Write-Caching sets the controller to
send a write-request completion signal
only after the data is written to the disk.
• nwc — No-Write-Caching specifies that
the controller does not send a write-
request completion signal after the data is
written to the disk.
NOTE: The -wpoption is optional and
can be added to the command line in any
order after the mandatory option
combination.
For SCSI controllers, the value of LUN should
always be 0.
For SAS controllers, the value of enclosure
can be non-zero, in which case you must
specify values for channel, target, and
enclosure.
