DESCRIPTION
The raidctl utility is a hardware RAID configuration tool
that supports different RAID controllers by providing a CLI(command-line interface) to end-users to create, delete or
display RAID volume(s). The utility can also used to setproperties of a volume, assign hot-spare (HSP) disks to
volumes or controllers, and to update firmware/fcode/BIOS for RAID controllers.

System Administration Commands raidctl(1M)
The raidctl utility requires privileges that are controlled
by the underlying file-system permissions. Only privileged
users can manipulate the RAID system configuration. If anon-privileged user attempts to run raidctl, the command
fails with an exit status of 1.The raidctl utility, as described in this man page, defines
a broad set of command line options to provide managementfor full-featured RAID controllers. However, support for a
given option depends on two elements: o the presence of a software driver o the firmware level of the RAID device The dependency on a software driver is due to the design ofraidctl. The utility is built on a common library that
enables the insertion of plug-in modules for different
drivers. Currently, the Solaris operating system is shippedwith a plug-in for the mpt driver. This plug-in does not
support all of the raidctl options. On a given storage dev-
ice, options might be further limited by the device's firmware level.The level of support for the various raidctl options cannot
be determined by raidctl. The user must rely on the documen-
tation for his RAID controller or hardware platform.Currently, raidctl Currently, raidctl provides some level of
support for the following RAID controllers: o LSI1020 SCSI HBA o LSI1030 SCSI HBA o LSI1064 SAS HBA o LSI1068 SAS HBA All of the above HBAs are maintained by the mpt driver, onX86-32/64 and SPARC platforms.
OPTIONS The following options are supported:-C "disks" [-r raid_level] [-z capacity] [-s stripe_size]
[-f] controller

System Administration Commands raidctl(1M)
Create a RAID volume using specified disks.When creating a RAID volume using this option, the iden-
tity of the newly created volume is automatically gen-
erated and raidctl reports it to the user.
The argument specified by this option contains the ele-
ments used to form the volume that will be created. Ele-
ments can be either disks or sub-volumes, where disks
are separated by space(s) and a sub-volume is a set of
disks grouped by parenthesis. All disks should be inC.ID.L expression (for example, 0.1.2 represents a phy-
sical disk of channel 0, target id 1, and logical unitnumber 2). The argument must match the RAID level speci-
fied by the -r option, even if it's omitted. This means
the argument can only be: for RAID 0 At least 2 disks for RAID 1 Only 2 disks for RAID 1E At least 3 disks for RAID 5 At least 3 disks for RAID 10At least 2 sub-volumes, each sub-volume must be
formed by 2 disks for RAID 50At least 2 sub-volumes, each sub-volume must be
formed by at least 3 disks, and the disk amount ineach sub-volume should be the same
For example, the expression "0.0.0 0.1.0" means that the 2 specified disks form a RAID volume, which can either be a RAID 0 or a RAID 1 volume. "(0.0.0 0.1.0)(0.2.0SunOS 5.11 Last change: 5 Feb 2009 3
System Administration Commands raidctl(1M)
0.3.0)" means that the first 2 disks and the last 2disks form 2 sub-volumes, and that these 2 sub-volumes
form a RAID 10 volume. See the EXAMPLES section for more
samples.The -r option specifies the RAID level of the volume
that will be created. Possible levels are 0, 1, 1E, 5,10, 50. If this option is omitted, raidctl creates a
RAID 1 volume by default.The -z option specifies the capacity of the volume that
will be created. The unit can be tera-bytes, giga-bytes,
or mega-bytes (for example, 2t, 10g, 20m, and so on). If
this option is omitted, raidctl calculates the maximum
capacity of the volume that can be created by the speci-
fied disks and uses this value to create the volume.The -s option specifies the stripe size of the volume
that will be created. The possible values are 512, 1k, 2k, 4k, 8k, 16k, 32k, 64k, or 128k. If this option isomitted, raidctl chooses an appropriate value for the
volume (for example, 64k). In some cases, the creation of a RAID volume may cause data on specified disks to be lost (for instance, onLSI1020, LSI1030, SAS1064, or SAS1068 HBAs), and raidctl
prompts the user for confirmation about the creation.Use the -f option to force the volume creation without
prompting the user for confirmation. The controller argument is used to identify which RAIDcontroller the specified disks belongs. The -l option
can be used to list the controller's ID number.-d [-f] volume
Delete the RAID volume specified as volume. The volume is specified in canonical form (for example, c0t0d0). When a volume is deleted, all data is lost. Therefore,unless the -f option is specified, raidctl prompts the
user for confirmation before deleting the volume. When a RAID 1 volume is deleted from a LSI1020, LSI1030, SAS1064, or SAS1068 HBA, the primary and secondary disks are "split". If the volume was in SYNCING state, the primary will contain the data, and the secondary will not. If the volume state was OPTIMAL, both disks will contain a complete image of the data.SunOS 5.11 Last change: 5 Feb 2009 4
System Administration Commands raidctl(1M)
-F filename [-f] controller...
Update the firmware running on the specifiedcontroller(s). The raidctl utility prompts the user for
confirmation of this action, unless the -f option is
provided.-a {set | unset} -g disk {volume | controller}
If the volume is specified, raidctl sets or unsets the
disk as a local hot-spare disk dedicated to the volume,
depending on the value specified by the -a option. If
the controller is specified, raidctl sets or unsets the
disk as a global hot-spare disk.
-p "param=value" [-f] volume
Change the property value for a given RAID volume. This option can be used to change cache write policy or to activate a volume. When changing the cache write policy,param should be the string wp (SET_WR_POLICY), and value
can be either on or off. When used to activate a volume, param should be state and value should be activate.Changing a RAID volume's property may affect the inter-
nal behavior of the RAID controller, so raidctl prompts
the user for a confirmation before applying the change,unless the -f option is specified.
-c [-f] [-r raid_level] disk1 disk2 [disk3...]
Create a volume using the specified disks. This is analternative to the -C option with similar functionality.
This option is preserved for compatibility reasons, but only works with LSI1020, LSI1030, SAS1064, and SAS1068 HBAs to create RAID 0, RAID 1, or RAID 1E volumes. Forother HBAs, the user can only use the -C option.
The -r option can be used to specify the RAID level of
the target volume. If the -r option is omitted, raidctl
will create a RAID 1 volume. Disks must be specified in Solaris canonical format (for example, c0t0d0). Creating a RAID 1 volume with this option replaces the contents of disk2 with the contents of disk1. When the user creates a RAID volume with this option,SunOS 5.11 Last change: 5 Feb 2009 5
System Administration Commands raidctl(1M)
the RAID volume assumes the identity of disk1. Other disks become invisible and the RAID volume appears as one disk. Creating a volume with this option is by default interactive. The user must answer a prompt affirmativelyto create the volume. Use the -f option to force the
volume creation without prompting the user for confirma-
tion.-l -g disk controller
Display information about the specified disk of the given controller. The output includes the following information: Disk Displays the disk in C.ID.L expression disk. Vendor Displays the vendor ID string. Product Displays the product ID string. Capacity Displays the total capacity of the disk. Status Displays the current status of disk. The status can be either "GOOD" (operating normally), "FAILED"(non-functional), or "MISSING" (disk not present).
HSPIndicates if the disk has been set as a global hot-
spare disk, local hot-spare disk, or a normal one.
If it is a local hot-spare disk, all volumes which
this disk is assigned to are displayed.SunOS 5.11 Last change: 5 Feb 2009 6

tional datum and might be unavailable in some cases.-l volume
Display information about the specified volume. The out-
put includes the following information: Volume Displays volume in canonical format. SubDisplays sub-volumes, if the specified volume is of
RAID 10 or RAID 50 volume. Disk Displays all disks that form the specified volume. Stripe Size Displays the stripe size of the volume. Status Displays the status of the specified volume, or thesub-volumes or disks that form the specified
volume. For an inactive volume, the status should be INACTIVE; otherwise it can be OPTIMAL (operatingoptimally), DEGRADED (operating with reduced func-
tionality), FAILED (non-functional), or SYNC (disks
are syncing). For a disk, the status can be GOOD, FAILED, or MISSING. CacheIndicates whether the cache is applied to I/O write activities. The cache can be either "ON" or "OFF".

attributes(5), mpt(7D) System Administration Guide: Basic Administration WARNINGS Do not create raid volumes on internal SAS disks if you aregoing to use the Solaris Multipathing I/O feature (also known as MPxIO). Creating a new raid volume under Solaris Multipathing will give your root device a new GUID which does not match the GUID for the existing devices. This will cause a boot failure since your root device entry in /etc/vfstab will not match. NOTES
The -z option is not supported on systems that use the mpt
driver and LSI RAID controllers.SunOS 5.11 Last change: 5 Feb 2009 15
