Creates a virtual disk comprising
the properties supplied. This option combination is mandatory. NOTE Create a bootable
virtual disk only from the disk drives of slot 0-3 of the system. 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. Example: A:>raidcfg -ctrl -ac=cvd
-c=2
-ad=1:4,1:8 -r=1 -ssz=32
-cp=d -rp=nra
-wp=wt -fd=1:1 RAIDCFG Command successful! |
|
-cp or cachepolicy |
d or e |
Valid arguments for disk cache
policy are: The -cp option is optional and
can be added to the command line in any order after the mandatory
option combination. |
|
-fd or failoverdrive |
ch:targ, ch:targ, ... or ch:targ:lun,... or ch:targ:enc
channel:target, or channel:target:l un, or channel:target: enclosure |
Sets the failover drive for the
virtual disk. The -fd option 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. |
|
-r or -raid |
0, 1, 5, 6, 10, 50, 60 |
Sets the RAID type or level for
the virtual disk. NOTE If this option is not
specified for any RAID controller, RAID 0 is taken as the default. The valid arguments are:
- 0 — RAID 0 uses data striping, which is writing data
in equal-sized segments across the array disks. RAID 0 does not provide
data redundancy.
- 1 — RAID 1 is the simplest form of maintaining redundant
data. In RAID 1, data is mirrored or duplicated on one or more drives.
- 5 — RAID 5 provides data redundancy by using data
striping in combination with parity information. Rather than dedicating
a drive to parity, the parity information is striped across all disks
in the array.
- 6 — RAID 6 is an extension of RAID 5 and uses extra
parity block. It uses block-level striping with two parity blocks
distributed across all member disks. RAID 6 provides protection against
double disk failures and failures while a single disk is rebuilding.
If there is only one array, RAID 6 may be a better option than a hot
spare disk.
- 10 — RAID 10 is a stripe of mirrors. Multiple RAID
1 mirrors are created, and a RAID 0 stripe is created over RAID 1
mirrors.
- 50 — RAID 50 is a dual-level array that uses multiple
RAID 5 sets in a single array. A single hard drive failure can occur
in each of the RAID 5 without any loss of data on the entire array.
Although the RAID 50 has increased write performance, when a hard
drive fails and reconstruction takes place, performance decreases,
data/program access is slower, and transfer speeds on the array are
affected.
- 60 — RAID 60 is a combination of RAID 6 and RAID
0. A RAID 0 array is striped across RAID 6 elements. It requires at
least 8 disks.

-rp or readpolicy |
ra, ara, nra, rc, nrc |
CAUTION If the controller is changed from SCSI to RAID mode,
expect data loss to occur. Back up any data you want to save before
changing the modes. Sets the SCSI read policy
for the virtual disk. Specify the SCSI read policy for the logical
drive. The valid arguments are:
- ra — (read-ahead) The controller reads sequential
sectors of the disk when seeking data.
- ara — (Adaptive Read-Ahead) The controller
initiates read-ahead only if the two most recent read requests accessed
sequential sectors of the disk. If subsequent read requests access
random sectors of the disk, the controller reverts to No-Read-Ahead
policy. The controller continues to evaluate whether read requests
are accessing sequential sectors of the disk and can initiate read-ahead
if necessary.
- nra — (No-Read-Ahead) The controller does
not read sequential sectors of the disk when seeking data.
NOTE The ra, ara, and nra 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
- rc — (Read-Caching) Enables read caching.
- nrc — (No-Read-Caching) Disables read caching.

-sp or spanlength |
<number> |
Creates a virtual disk comprised
of the properties supplied. The -sp option is optional
and can be added to the command line in any order after the mandatory
option combination. NOTE Spanlength is applicable
only for RAID 50 and RAID 60. The minimum permissible spanlength value
for RAID 50 is 3 and for RAID 60 is 4. The number of array disks for
creating a virtual disk should not be a prime number and should be
divisible by the specified spanlength. NOTE For creating RAID 10,
the PERC 9 firmware suggests the layout (number of array disks) with
uneven span (spans with unequal number of array disks), though in
a span the number of disks remain even. For example, for 32 disks,
RAID 10 is created with all the disks in one span and for 34 disks,
RAID 10 is created with 16 disks in one span and 18 disks in the other span. 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. |

-ssz or stripesize |
<number> |
Sets the stripe size for the virtual
disk. The stripe size is the amount of array disk space used on each
array disk included in the stripe. A valid argument is a number that
is less than the size of the virtual disk. The -sszoption is optional and can be added to the command line in any order
after the mandatory option combination. However, do not specify a
unit for stripe size when creating virtual disks. The unit is always
displayed in KB. 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. |

-str or strict |
<number> |
Strict (-str parameter) is the
percentage of expected array disk utilization. Example: A:> raidcfg -ctrl -ac=
cvd -c=0 -ad=0:0,0:1 -
r=1 -str=20 If the unused portion of an
array disk is greater than the mentioned percentage, raidcfg aborts. 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. |

-sz or -size |
<number> |
Sets the maximum size of the virtual
disk in MB or GB. A valid argument is a number representing the maximum
size for the virtual disk. The -szoption is optional
and can be the added to the command line in any order after the mandatory
option combination. The minimum virtual disk size
that you can create for various controllers is as follows:
- For PERC 5 controllers:
- RAID 0: 100 MB
- RAID 1: 100 MB
- RAID 5: 100 MB
- For PERC 6 controllers:
- RAID 0: 100 MB
- RAID 1: 100 MB
- RAID 5: 100 MB
- RAID 6: 100 MB
- RAID 60: 100 MB
- For PERC 7, PERC 8, and PERC 9 controllers:
- RAID 0: 100 MB
- RAID 1: 100 MB
- RAID 5: 100 MB
- RAID 6: 100 MB
- RAID 10: 100 MB
- RAID 50: 100 MB
- RAID 60: 100 MB
- Software RAID controllers:
- RAID 0: 100 MB
- RAID 1: 100 MB
- RAID 5: 100 MB
- RAID 10: 100 MB
NOTE If this
option is not provided, RAIDCFG determines the maximum virtual disk
size and creates it. |

-vdpi or vdiskprotectioninfo |
0,1 |
Creates a virtual disk with the
T10 Protection Information (PI) feature enabled. NOTE This option is supported
only on PERC 9 controllers. Example: A:>raidcfg -ctrl -ac=cvd
-c=2
-ad=1:4,1:8 -vdpi=1 RAIDCFG Command successful! |
|
-wp or writepolicy |
wb, wt, wc, nwc, fwb |
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, PERC 8, and PERC 9
- 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.
- fwb — Force write-back caching, enables the
write cache regardless of whether the controller has a battery. If
the controller does not have a battery and force write-back caching
is used, data loss may occur in the event of a power failure
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. |

-sf or secureflag |
0, 1 |
Creates a secured virtual disk
on controllers with encryption capability and encryption key. Example: A:>raidcfg -ctrl -ac=cvd
-c=2
-ad=1:4,1:8 -sf=1 RAIDCFG Command successful! |
