display [-p] pathname...

Display configuration information for the specified units or display performance information for the specified SPARCstorage Array controller. If pathname specifies the controller, the configuration information is displayed for all disks in the SPARCstorage Array. For each drive that has fast write enabled, (FW) are displayed after the drive identification.

-p

Display performance information for the specified SPARCstorage Array controller. The accumulation of the performance statistics must be enabled using the perf_statistics subcommand before displaying the performance information. If not enabled, all of the I/Os per second are displayed as zeros.

The performance display reports the following information:

BUSY

How busy the controller in the SPARCstorage Array is, expressed as a percentage.

IOPS

The total I/Os per second for the SPARCstorage Array.

entries for each disk

The total number of I/Os per second.

download -f filename pathname

download -w wwn pathname

Download an image to the SPARCstorage Array controller.

-f

Download the prom image specified by filename to the SPARCstorage Array controller FEPROMs. When the download is complete, the SPARCstorage Array must be reset in order to use the downloaded code. Note that the download subcommand modifies the FEPROM on the SPARCstorage Array and should be used with caution.

-w

Change the SPARCstorage Array controller's World Wide Name. wwn is a 12 digit hex number, leading zeros required. The new SPARCstorage Array controller's image have the least significant 6 bytes of the 8-byte World Wide Name modified to wwn.

fast_write [-s] -c pathname

fast_write [-s] -d pathname

fast_write [-s] -e pathname

Enable or disable the use of the NVRAM to enhance the performance of writes in the SPARCstorage Array. pathname may refer to the SPARCstorage Array controller or to an individual disk.

-c

Enable fast writes for synchronous writes only.

-d

Disable fast writes.

-e

Enable fast writes.

-s

Save the state that is currently being requested so it persists across power-cycles.

fc_s_download [-f fcode-file]

Download the fcode contained in the file fcode-file into all the FC/S Sbus Cards. This subcommand is interactive and expects user confirmation before downloading the fcode. When invoked without the [-f fcode-file] option, the current version of the fcode in each FC/S Sbus card is printed. Note that the fc_s_download subcommand should be used only in single-user mode; otherwise the FC/S card could be reset.

insert_device pathname

Guide user through hot insertion of a disk device.

This subcommand only applies to the RSM. See NOTES for hot plugging limitations.

perf_statistics -d pathname

perf_statistics -e pathname

Enable or disable the accumulation of performance statistics for the specified SPARCstorage Array controller. The accumulation of performance statistics must be enabled before using the display -p subcommand. This subcommand can be issued only to the SPARCstorage Array controller.

-d

Disable the accumulation of performance statistics.

-e

Enable the accumulation of performance statistics.

purge pathname

Purge any fast write data from NVRAM for one disk, or all disks if the controller is specified. This option should be used with caution, usually only when a drive has failed.

release pathname

Release a reservation held on the specified controllers or disks. When HA (High_Availability) Software is running on a system, do not use this subcommand to release a disk on an SSA. Doing so could cause problems for the HA software.

remove_device pathname

Guide user through hot removal of a disk device.

This subcommand only applies to the RSM. See NOTES for hot plugging limitations.

replace_device pathname

Guide user through hot replacement of a disk device.

This subcommand only applies to the RSM. See NOTES for hot plugging limitations.

reserve pathname

Reserve the specified controllers or disks for exclusive use by the issuing host. When HA (High_Availability) Software is running on a system, do not use this subcommand to reserve a disk on an SSA. Doing so could cause problems for the HA software.

set_boot_dev [-y] pathname

Set the boot-device variable in the PROM to the physical device name specified by pathname which can be a block special device or the pathname of the directory on which the boot file system is mounted. This subcommand normally runs interactively and requests confirmation for setting the default boot device in the PROM. The -y option can be used to run it in non-interactive mode, in which case no confirmation is requested or required.

start [-t tray-number] pathname

Spin up the specified disks. If pathname specifies the controller, this action applies to all disks in the SPARCstorage Array.

-t

Spin up all disks in the tray specified by tray-number. pathname must specify the controller.

stop [-t tray-number] pathname

Spin down the specified disks. If pathname specifies the controller, this action applies to all disks in the SPARCstorage Array.

-t

Spin down all disks in the tray specified by tray-number. pathname must specify the controller.

sync_cache pathname

Flush all outstanding writes for the specified disk from NVRAM to the media. If pathname specifies the controller, this action applies to all disks in the SPARCstorage Array.

The SPARCstorage RSM tray is addressed by the using the logical or physical path of the SES device or specifying the controller followed by the tray number if that controller has multiple trays. The controller is addressed by cN or the physical path to the SPARCstorage Array's controller.

See ses(7D) for more information about environmental sensor cards and associated devices.

These subcommands also work with RSM trays directly attached to wide differential SCSI controllers.

alarm pathname | controller tray-number

Display the current state of the audible alarm.

alarm_on pathname | controller tray-number

alarm_off pathname | controller tray-number

Enable or disable the audible alarm for this enclosure.

alarm_set pathname | controller tray-number [seconds]

Set the audible alarm setting to seconds.

env_display pathname | controller tray-number

Display the environmental information for the specified unit.

led pathname

Display the current state of the led for the specified disk.

led_on pathname

led_off pathname

Turn on or off the led for this disk.

power_off pathname | controller tray-number

Power down this RSM. The RSM will need to be powered back on manually.

This subcommand does not work with RSMs directly attached to wide differential SCSI controllers.

See NOTES for limitations of these subcommands. Only users that are knowledgeable about the systems they are managing should use the expert mode subcommands.

For the following subcommands that work on a bus if a disk is specified then the bus that disk attached to is used.

bus_getstate pathname

Get and display the state of the specified bus.

bus_quiesce pathname

Quiesce the specified bus.

bus_reset pathname

Reset the specified bus.

bus_resetall pathname

Reset the specified bus and all devices on that bus.

bus_unquiesce pathname

Unquiesce the specified bus.

dev_getstate pathname

Get the state (online or offline) of the specified device.

dev_reset pathname

Reset the specified device.

offline pathname

Turn the specified disk offline.

online pathname

Turn the specified disk online.

An example of using the expert mode hot plugging subcommands to hot remove a disk on a SSA follows. See NOTES for hot plugging limitations.

The first step reserves the SCSI device so that it can't be accessed via its second SCSI bus:

example# ssaadm reserve /dev/dsk/c1t8d0s2

The next two steps take the disk to be removed offline then quiesce the bus:

example# ssaadm -e offline /dev/dsk/c1t8d0s2 example# ssaadm -e bus_quiesce /dev/dsk/c1t8d0s2

The user then removes the disk and continues by unquiescing the bus, putting the disk back online, then releasing it:

example# ssaadm -e bus_unquiesce /dev/dsk/c1t8d0s2 example# ssaadm -e online /dev/dsk/c1t8d0s2 example# ssaadm release /dev/dsk/c1t8d0s2

ssaadm: can't acquire "PATHNAME": No such file or directory
