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:
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.
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.
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.
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.
In the left navigation pane, select CMM (Chassis Monitoring Module).
The ILOM Version Information page appears.
Select the System Information tab, and then the Components tab.
The Component Management page appears.
Verify that the selected component has returned the expected feedback.
See the table below.
Log in to the ILOM CLI.
For a list of components in your system, type:
show /CH
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
Verify that the selected component has returned the expected feedback.
See the table below.
The following table describes how to verify that the hot-insert operation was successful.
Component |
Expected Feedback |
---|---|
Server Modules (blades) |
|
Network Express Modules (NEM) |
|
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) |
|
Power Supplies |
|
Front Fan Modules (Sun Blade 8000 Chassis only) |
|
Rear Fan Modules |
|
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. |
