Verify Hot-Insert Operation

You can replace many components in the chassis while the system is running by using a hot-plug procedure. To determine which modules are hot-pluggable, see About Hot-Pluggable Components.

To insert modules into the chassis while it is powered-on, you need to:

  1. Prepare the module for hot-insert and install the module. For more information, see Prepare Components for Hot-Remove OperationSee the Service and Upgrades section for information about component installation.

  2. Verify in ILOM (Web or CLI interface) that the module's Ready-to-Remove status changed to expected Not Ready status. See the table below.

Note

Some operating systems, some PCIe ExpressModules (EMs), and some Network Express Modules (NEMs) do not support a hot-plug operation. Check your operating system documentation, the I/O module documentation, and the Sun Blade 8000 Series Product Notes to verify the hot-plug support.

Status Verification - ILOM Web Interface

  1. Log in to the ILOM web interface using the IP address of the active Chassis Monitoring Module.

    The first page of the ILOM web interface appears.

  2. In the left navigation pane, select CMM (Chassis Monitoring Module).

    The ILOM Version Information page appears.

  3. Select the System Information tab, and then the Components tab.

    The Component Management page appears.

  4. Verify that the selected component has returned the expected feedback.

    See the table below.

Status Verification - ILOM CLI Interface

  1. Log in to the ILOM CLI.

  2. For a list of components in your system, type:

    show /CH

  3. To verify that the component Ready to Remove status has changed to Not Ready, type:

    show /CH/component

    The system returns this message:

    prepare_to_remove_status=Not Ready

  4. Verify that the selected component has returned the expected feedback.

    See the table below.

Verifying Component Status

The following table describes how to verify that the hot-insert operation was successful.

Component

Expected Feedback

Server Modules (blades)

  • When the blade is inserted, the service processor is powered on.

  • Green OK LED goes to Slow Blink while the service processor boots, then it goes to Standby Blink.

  • When the green OK LED goes to Standby Blink, the blade will power on by default if the blade's last power state was On, and the green OK LED goes to Solid On. If you have disabled the blade power-on option, you can power on the blade using the blade Power button or using the ILOM interfaces. See Power Blade On or Off.

  • Ready to Remove status shows Not Ready in the ILOM interfaces.

Network Express Modules (NEM)

  • Green OK LED goes to Standby Blink.

  • Activate the NEM by pressing the Attention button, and the green OK LED goes to Slow Blink.

  • When all links to active blades have been made, the green OK LED goes to Solid On.

  • Ready to Remove status shows Not Ready in the ILOM interfaces.

ExpressModules (EM; Sun Blade 8000 Chassis only)

EM hot-plug insertion must be initiated by pressing the Attention button on the EM. EMs cannot be hot-plugged through the ILOM interfaces. To insert an EM using a hot-plug operation, see Replace ExpressModule (Sun Blade 8000 Chassis).

Chassis Monitoring Module (CMM)

  • When the CMM is inserted, it is automatically brought online.

  • Green OK LED goes to Slow Blink while the CMM boots, then to Solid On when the boot is complete.

  • Ready to Remove status shows Not Ready in the ILOM interfaces.

Power Supplies

  • When the power supply is connected to its power source, the green AC-OK LED lights Solid On.

  • If the chassis is powered on, then the green DC-OK LED lights Solid On.

  • Ready to Remove status shows Not Ready in the ILOM interfaces.

Front Fan Modules (Sun Blade 8000 Chassis only)

  • If the chassis is powered on, the green OK LED lights Solid On and the fans start to spin.

  • Ready to Remove status shows Not Ready in the ILOM interfaces.

Rear Fan Modules

  • If the chassis is powered on, the green OK LED lights Solid On and the fans start to spin.

  • Ready to Remove status shows Not Ready in the ILOM interfaces.

Hard Disk Drives (on the blades)

When you insert a drive into a powered-on blade, the drive is brought online automatically. If you have properly hot-inserted a drive, the green OK/Activity indicator lights Solid On.
