DESCRIPTION
The command is a command line configuration tool for the HP SmartArray
RAID Controller Family. This command provides the ability to create a
logical drive, add a spare drive to existing logical drive, display
configuration, delete a logical drive, and clear configuration. This
command also enables the cache when it is used to create the first log‐
ical drive on the SmartArray RAID Controller. Furthermore it allows the
option of changing the percentage of total cache size used for read
caching and write caching. The auto-fail missing disks at boot feature
can be enabled or disabled using this command.
Prerequisites
needs to be able to create the /tmp/saconfig.lock file when it starts
executing. This prevents multiple users from running This lock file is
removed when exits.
Security Restrictions
requires either the superuser privilege or and privileges. See privi‐
leges(5) for more information about privileged access on systems that
support fine-grained privileges.
Options
recognizes the following options and parameters as indicated in the
SYNOPSIS section above.
<device_file> To specify the device file for the SmartArray
RAID Controller. The device file is as dis‐
played by the command for the appropriate
SmartArray RAID Controller.
With no other options, displays size and sta‐
tus for all physical drives and RAID level,
size, and status for all logical drives.
With the option saconfig displays size and
status for all physical drives and RAID level,
size, and status for all logical drives. But
the persistent device files (see intro(7))
will be displayed as against legacy device
files in the absence of this option.
-R <RAID_level> To create a logical drive with the specified
RAID level. The supported RAID levels are 0,
1, 1+0, 5, and ADG. The lowest logical drive
number not already in use will be given to the
newly created logical drive, starting from 0.
To determine the hardware path and device file
for the logical drive, use the command. The
logical drives are displayed in the same order
as in the output.
RAID 1+0 logical drive requires even number of
physical drives (minimum of 2). To achieve
optimal fault tolerance, it is best to specify
the same number of physical drives per channel
if possible when creating a RAID 1+0 logical
drive. This ensures the physical drives in
each mirrored pairs would be on different
channels.
-S <stripe_size> To specify the stripe size for the logical
drive to be created. The supported stripe
sizes are 8, 16, 32, 64, 128, and 256 (KB).
128 and 256 stripe sizes are not available for
RAID 5 or ADG logical drive. If this option is
not used to specify the stripe size, default
stripe size will be used to create the logical
drive. For RAID 0 and 1+0 logical drive, the
default size is 128. For RAID 5 and ADG logi‐
cal drive, the default size is 16.
-p <physical_drive_id> To specify the SCSI physical disk. It can be
represented as <channel_id>:<target_id> (e.g.,
4:12). Valid channel numbers are between 1 and
4. Valid target numbers are between 0 and 15.
To specify the SAS/SATA physical disk. It can
be represented as either <connector>:<enclo‐
sure>:<bay> (e.g., 2I:1:10) or <wwid> (e.g.,
0x500000e010f16432).
-s <physical_drive_id> To specify a spare drive to be included in the
logical drive configuration. Refer <physi‐
cal_drive_id> to -p option.
-c <capacity> To specify the size in GB of a logical drive
to be created.
-A <logical_drive_num> To specify which logical drive to add spare
drive to.
-e <low | medium | high> To change the expand priority of controller to
one of Low, Medium, High. When there are no
logical drives, expand priority cannot be
changed. When the configuration is cleared, or
the last logical drive is deleted, the subse‐
quent logical drive creation will change the
expand priority value of the controller to
medium.
-r <low | medium | high> To change the rebuild priority of controller
to one of Low, Medium, High. When there are no
logical drives, rebuild priority cannot be
changed. When the configuration is cleared, or
the last logical drive is deleted, the subse‐
quent logical drive creation will change the
rebuild priority value of the controller to
high.
-P <default | shortest | longest>
To change the path selection method by the
controller firmware. If it is set to default,
firmware will select the Active path on its
own. If the selection method is set to short‐
est, firmware will select the shortest path as
the Active Path. If the path selection method
is longest, firmware will select the longest
path as the Active Path. All multi path con‐
figurations are Active-Standby configurations.
-D <logical_drive_num> -s <physical_drive_id>
To delete the spare drive from the specified
logical drive.
-D <logical_drive_num> -s all
To delete all of spare drives from the speci‐
fied logical drive.
-D <logical_drive_num> To delete the specified logical drive.
-D all To clear configuration.
-C <read_caching_percentage>
To specify the percentage of total cache size
to be used for read caching. The remaining
percentage will be used for write caching.
Valid read caching percentage numbers are 0,
25, 50, 75, and 100 (%).
-F on To enable auto-fail missing disks at boot fea‐
ture.
-F off To disable auto-fail missing disks at boot
feature.
-I -p <physical_drive_id> [-p <physical_drive_id> ...]
To identify SAS/SATA physical drive(s) by LED.
-I -l <logical_drive_num>
To identify a SAS/SATA logical drive by LED.
-E <logical_drive_num> -c <capacity>
To extend the capacity of the specified logi‐
cal drive up to larger capacity. The capacity
is in GB.
-E <logical_drive_num> -p <physical_drive_id> [-p <physical_drive_id>
...]
To expand the specified logical drive and oth‐
ers in an array by physical drive(s).
-M <logical_drive_num> -R <RAID_level> [-S <stripe_size>]
To perform RAID level [with stripe size]
migration on the specified logical drive. The
stripe size is in KB.
-M <logical_drive_num> -S <stripe_size>
To perform stripe size migration on the speci‐
fied logical drive. The stripe size is in KB.
Logical Drive State Definitions
All physical disks in the logical drive are operational.
Some possible causes:
Multiple physical disks in a fault-tolerant (RAID 1, 1+0,
5, ADG) logical
drive have failed.
One or more disks in a RAID 0 logical drive have failed.
Cache data loss has occurred.
Array expansion was aborted.
The logical drive is temporarily disabled because another
logical drive
on the controller had a missing disk at power-up.
Also known as "degraded" state. A physical disk in a fault tolerant
logical
drive has failed. For RAID 1, 1+0 or 5, data loss may
result if a second disk should fail. For RAID ADG, data
loss may result if two additional disks should fail.
A replacement disk is present, but rebuild hasn't started yet (another
logical
drive may be currently rebuilding). The logical drive will
also return to this state if the rebuild had been aborted
due to unrecoverable read errors from another disk.
One or more physical disks in this logical drive are being rebuilt.
While the logical drive was in a degraded state, the system was powered
off and
a disk other than the failed disk was replaced. Shut off
the system and replace the correct (failed) disk.
While the system was off, one or more disks were removed. Note: the
other
logical drives are held in a temporary "failed" state when
this occurs.
The data in the logical drive is being reorganized because:
Physical disks have been added to the array (capacity
expansion).
The stripe size is being changed (stripe-size migration).
The RAID level is being changed (RAID-level migration).
A capacity expansion operation is in progress (or is queued up) that
will make
room on the disks for this new logical drive. Until room
has been made on the physical disks, this newly configured
logical drive cannot be read or written.
The logical drive is waiting to undergo data reorganization (see
EXPANDING above).
Possible causes for the delay are a rebuild or expansion
operation may already be in progress.
Physical Disk State Definitions
The physical disk is configured in one or more logical drives and is
operational.
The physical disk is configured as a spare disk.
The physical disk has not been configured in any logical drives.
The configured physical disk has failed.
Return Value
returns the following values:
Successful completion.
Command line syntax error.
Incompatible CISS driver API.
Failure opening a file.
Other error.
