lsenclosurepsu

Use the lsenclosurepsu command to view information about each power-supply unit (PSU) in the enclosure.

Syntax

lsenclosurepsu [ -filtervalueattribute_value ] [ -filtervalue? ] [ -delimdelimiter ] [ { | | -psupsu_id } enclosure_id ]

Parameters

-delim delimiter
(Optional) By default in a concise view, all columns of data are space-separated. The width of each column is set to the maximum possible width of each item of data. In a detailed view, each item of data has its own row, and if the headers are displayed, the data is separated from the header by a space. The -delim parameter overrides this behavior. Valid input for the -delim parameter is a one-byte character. If you enter -delim : on the command line, the colon character (:) separates all items of data in a concise view; for example, the spacing of columns does not occur. In a detailed view, the data is separated from its header by the specified delimiter.
-filtervalueattribute=value
(Optional) Specifies a list of one or more filters. Only objects with a value that matches the filter attribute value are displayed.
Note: Some filters allow the use of a wildcard when you enter the command. The following rules apply to the use of wildcards:
  • The wildcard character is the asterisk (*).
  • The command can contain a maximum of one wildcard.
  • When you use a wildcard, enclose the filter entry within double quotation marks (""): 
    lsenclosurepsu -filtervalue "psu_id=1"
-filtervalue?
(Optional) Displays the valid filter attributes for the -filtervalue parameter:
  • enclosure_id
  • psu_id
  • status
-psu psu_id
(Optional) Valid only when the enclosure_id is specified. Provides a detailed view of the PSU for the specified enclosure.
enclosure_id
(Optional) Lists the PSUs for the specified enclosure.

Description

This command enables you to view information about each power-supply unit (PSU) in the enclosure. Table 1 shows the possible outputs:
Table 1. lsenclosurepsu output
Attribute Description
enclosure_id Indicates the ID of the enclosure containing the PSU.
psu_id Indicates the ID of the PSU in the enclosure.
status Indicates the status of the power and cooling unit in the enclosure:
  • online indicates a PSU is present and working normally
  • offline indicates a PSU cannot be detected
  • degraded indicates a PSU is present but not working normally
input_failed
  • on indicates no usable input power is detected from the power distribution unit.
  • off indicates the input power is OK.
output_failed
  • on indicates no usable output power is detected from the distribution unit.
  • off indicates the output power is OK.
input_power
  • ac indicates the power supply requires AC power input.
  • dc indicates the power supply requires DC power input.
  • unknown indicates the power supply is not known or cannot be determined.
fan_failed
  • on indicates that if the AC, DC, and fan LEDs are all on, there is a PSU fault. If only the fan LED is on, then there is a fan failure.
  • off indicates the fans in this PSU are OK.
redundant Indicates (yes or no) whether you can remove the power supply:
  • If the PSU is on an expansion enclosure, the other PSU must be online.
  • If the PSU is on a control enclosure, the other PSU must be online and the battery on that PSU must contain enough charge to allow the canisters to dump state and cache data before shutting down.
Note: If the redundant status is no during software update, the system might be stalled for several hours (on a Lenovo Storage V7000 Gen1 system).
error_sequence_number Indicates the error log (or event log) number of the highest priority error for this object. This is typically blank; however, if there is a problem (for example, the status is degraded), then it contains the sequence number of that error event.
FRU_part_number Indicates the FRU part number of the PSU.
FRU_identity Indicates the 11S number, combining the manufacturing part number and the serial number.
firmware_level_1 Indicates the version of the microcode image (power supply firmware version) installed on the power supply.
firmware_level_2 Indicates the version of the power supply metadata (power supply vital product data, or VPD, version) installed on the power supply.
Note: This field might not be applicable for some systems and is blank for all PSU types.
firmware_level_3 Indicates the version of the secondary microcode image installed on the enclosure's High Efficiency (HE) power supply unit (PSU).
Note: This field might not be applicable for some systems and is blank for all PSU types.
