Display the Boot Media Device Health Status

Availability: This command is available to cluster administrators at the admin privilege level.

Description

The system controller bootmedia show command displays details of the bootmedia devices present in all the nodes in a cluster. These commands are available for 80xx, 25xx and later systems. Earlier models are not supported. By default, the command displays the following information about the bootmedia:

  • Node name

  • Display name

  • Vendor ID

  • Device ID

  • Memory size

  • Bootmedia state

  • Health monitor status

To display more details, use the -instance parameter.

Parameters

{ [-fields <fieldname>,…​]

Selects the fields that you specify.

| [-instance ] }

Displays detailed information for all the bootmedia devices.

[-node {<nodename>|local}] - Node

Selects the bootmedia device that is present on the specified node.

[-serial-num <text>] - Serial Number

Selects the bootmedia devices with the specified serial number.

[-vendor-id <Hex Integer>] - Vendor ID

Selects the bootmedia devices with the specified vendor ID.

[-device-id <Hex Integer>] - Device ID

Selects the bootmedia devices with the specified device ID.

[-display-name <text>] - Display Name

Selects the bootmedia devices with the specified display name.

[-unique-name <text>] - Unique Name

Selects the bootmedia device with the specified unique name.

[-monitor {node-connect|system-connect|system|controller|chassis|cluster-switch|example|ethernet-switch}] - Health Monitor Name

Selects the bootmedia devices with the specified health monitor.

[-usbmon-status {present|not-present}] - Bootmedia Health Monitor

Selects the bootmedia devices with the specified USBMON status.

[-device-state {good|warn|bad}] - Bootmedia State

Selects the bootmedia devices with the specified device state.

[-size <integer>] - Max Memory Size (MB)

Selects the bootmedia devices with the specified memory size.

[-health {ok|ok-with-suppressed|degraded|unreachable|unknown}] - Status

Selects the bootmedia devices with the specified health monitor status.

[-is-nvme {true|false}] - Is NVMe Boot Media

Selects the boot media technology. If the value is "true", the boot media uses NVMe technology.

[-nvme-percent-used <integer>] - NVMe Percentage Used

Selects the NVMe boot media with the specified percentage of rated life used by the solid-state device (SSD). When an SSD reaches 100% of rated life, it might not be able to retain data while powered off for long periods of time.

[-nvme-available-spare <integer>] - NVMe Available Spare

Selects the NVMe boot media with the specified percentage of available spare blocks. When all spare blocks are consumed on the SSD, i.e. when this parameter reaches 0%, the system can no longer write data to the solid-state device (SSD).

[-nvme-spare-threshold <integer>] - NVMe Spare Threshold

Selects the NVMe boot media with the specified "low spare blocks" threshold percentage. System health monitor alerts are generated when the available spare blocks on the SSD cross below this threshold.

Examples

The following example displays the information of the boot media present in all the nodes in a cluster:

cluster1::> system controller bootmedia show
Size Bootmedia
Node          Display Name         Vendor ID Device ID    (MB) State     Status
------------- -------------------- --------- --------- ------- --------- ------
node1         Micron Technology          634       655    1929 good      ok
              0x655
node2         Micron Technology          634       655    1929 good      ok
              0x655

The example below displays the detailed information about the bootmedia present in a node.

cluster1::> system controller bootmedia show -instance -node node1

           Unique Name: Micron Technology 0x655 (ad.0)
   Health Monitor Name: controller
 USBMON Health Monitor: present
       Bootmedia State: good
Max memory size(in MB): 1929
                Status: ok
               Is NVMe: true
  NVMe Percentage Used: 0
  NVMe Available Spare: 100
