IPMI BMC configuration

Use the IPMI BMC configuration page to customize settings for communicating with IPMI-enabled devices. The features described below are available for in-band devices; if a device is out of band, only the power configuration and BMC user settings are available.

CAUTION: It is strongly recommended that you do not change IPMI settings unless you are familiar with the IPMI specification and understand the related technologies involved in these settings. Improper use of these configuration options may prevent Management Suite from successfully communicating with IPMI-enabled devices.

The following configuration options are available:

Changing watchdog timer settings

IPMI provides an interface for the BMC watchdog timer. This timer can be set to expire periodically, and is configured to initiate certain actions if it expires (such as power cycling). Management Suite is configured to reset the timer periodically so it does not expire; if the device becomes unavailable (for example, it is powered down or hangs), the timer is not reset and it then expires, which initiates the action.

You can specify how much time to allow before the timer expires and select an action to perform if it does expire. You can choose to take no action, do a hard reset (shut down and restart of the device), power down the device gracefully, or run a power cycle (power down gracefully and then start up again).

You can also set the BMC to stop broadcasting ARP (Address Resolution Protocol) messages while the watchdog timer is enabled, which can reduce the amount of network traffic being generated. If you suspend ARPs, they will automatically resume if the watchdog timer expires.

To change watchdog timer settings
  1. In the Management Suite network view, right-click the IPMI device and select Real-time inventory and monitoring.
  2. In the left navigation pane of the real-time inventory console, click Hardware configuration.
  3. Expand IPMI BMC configuration and click Watchdog timer.
  4. Select Turn on the watchdog timer to enable the timer.
  5. Specify the frequency of checking the timer (number of minutes or seconds).
  6. Select an action to initiate when the watchdog timer expires.
  7. If you want the BMC to stop broadcasting ARP messages while the watchdog timer is enabled, select Suspend BMC ARPs.
  8. Click Apply.
  9. If you have changed the watchdog timer settings, you can revert to the default settings by clicking Restore defaults.

Changing power configuration settings

When power is lost on an IPMI-enabled computer, you can specify what action should be taken when power is restored. We recommend that you restore the computer to whatever state it was in at the time power was lost, but you can also choose to keep it powered off or always power up the computer.

To change power configuration settings
  1. In the Management Suite network view, right-click the IPMI device and select Real-time inventory and monitoring.
  2. In the left navigation pane of the server information console, click Hardware configuration.
  3. Expand IPMI BMC configuration and click Power configuration.
  4. Select an option for when power is restored.
  5. Click Apply.
  6. If you have changed the power configuration settings, you can revert to the default settings by clicking Restore defaults.

Changing BMC user settings

Management Suite authenticates to a BMC with a user name/password combination that is unique to the BMC (separate from any other Management Suite user names). Management Suite reserves the first user name so it can always communicate with the BMC. If the BMC allows other user names to be defined, you can define user names with passwords for BMC authentication.

You can also specify privilege levels for each user. For advanced IMMs, you can specify protocol privilege levels (telnet, http, and https) for each channel.

CAUTION: Use extreme caution when making changes to these settings. Erroneous settings can disable the device's BMC communication with this product.

To change BMC user settings
  1. In the Management Suite network view, right-click the IPMI device and select Real-time inventory and monitoring.
  2. In the left navigation pane of the server information console, click Hardware configuration.
  3. Expand IPMI BMC configuration and click User settings.
  4. To clear the data for a user name, click the index number and click Clear.
  5. To add or change a username, click the index number and click Edit.
  6. Type a user name.
  7. To set a password, select the Set password check box, then type the password and confirm it.
  8. Select the privilege levels for LAN and serial access.
  9. Click Save changes.

Changing the BMC password

Management Suite authenticates to a device's BMC using the default user name (user 1 and password). You can't change the user name but you can change its password. When you change this password setting, the change is saved in the database and on the BMC.

To change the default BMC password
  1. In the Management Suite network view, right-click the IPMI device and select Real-time inventory and monitoring.
  2. In the left navigation pane of the server information console, click Hardware configuration.
  3. Expand IPMI BMC configuration and click Password.
  4. Type the new password and then confirm it.
  5. Click Apply.

Changing LAN configurations

IPMI messages can be carried directly from the BMC over a LAN interface in addition to the device's system interface. Enabling LAN communication allows the core server to receive IPMI-specific alerts even if the device is powered down. The core server maintains this communication as long as the device has a physical network connection with a valid network address, and as long as the device's main power remains connected.

CAUTION: If you choose to set a custom configuration for LAN or serial communication to the BMC, use extreme caution when making changes to the settings. Erroneous settings can disable the device's BMC communication with this product.

If you have a LAN channel defined, you can use the default settings for the device's BMC, or you can change the IP address and gateway settings. Use these options to configure destinations for the SNMP traps sent by the BMC for each platform event trap (PET) event.

You can also change SNMP community string settings for sending alerts over LAN. When configuring these settings, you must specify the SNMP community string used for SNMP authentication. For each configuration, you can edit the trap destination information to specify where and how traps are sent, and whether they are acknowledged.

To set properties for LAN channel configuration
  1. In the Management Suite network view, right-click the IPMI device and select Real-time inventory and monitoring.
  2. In the left navigation pane of the server information console, click Hardware configuration.
  3. Expand IPMI BMC configuration and click LAN configuration.
  4. Select Always available in the LAN communication list to keep access to the BMC open. If you select Disabled you will not have LAN access to the BMC when the device is out of band.
  5. Select the User privilege level for the channel: Administrator-level has access to all commands, while User-level is limited to read-only access (you will have a restricted feature set if you select User-level).
  6. Select Permanently turn off BMC ARPs to turn off Address Resolution Protocol messages from the BMC. This reduces network traffic but can prevent communication with the BMC when the device is out of band.
  7. Select Turn off ARP responses to stop the BMC from sending ARP message responses when the OS is not available. If you enable this setting you might prevent communication with the BMC when the device is out of band.
  8. IP settings for the LAN channel are automatically set if the BMC is in sync with the OS channel. If not, the check box under the IP settings tab is selected. You can leave the box selected to use DHCP settings provided automatically, or you can clear the check box and edit the text fields with static settings. It is generally preferable to use automatic settings.
  9. Click the Send alerts over LAN tab to configure SNMP community string settings (see details below).
  10. Click Apply to save your changes.

NOTE: If you click the Restore defaults button on this page, the settings under the Properties for LAN channel heading are reset to their default values, but other settings on the page are not changed. If you change any data on the IP settings tab and click Apply, you would need to manually reset those settings.

To change Send alerts over LAN properties
  1. Open the LAN configuration page (steps 1-3 above).
  2. Click the Send alerts over LAN tab.
  3. Select the Enabled check box to enable sending SNMP alerts.
  4. Specify the SNMP community string to be used for SNMP authentication.
  5. To configure the trap destinations, double-click the index number to open a Properties dialog box.
  6. Select Enable this alert destination. Specify the IP address to which the BMC will send alerts, as well as the corresponding MAC address.
  7. Specify the number of times to retry, how frequently to retry, and the preferred gateway to use.
  8. If you want the alerts to be acknowledged (which increases the amount of network traffic that is generated), select the Acknowledge alerts check box.
  9. Click OK.
  10. At the LAN configuration page, click Apply when all settings are complete.

Changing Serial Over LAN (SOL configurations)

Use SOL (Serial Over LAN) configuration options to customize serial modem settings for special uses, such as redirecting BIOS POST messages to the serial port. If the BMC is required to dial out over a modem connection, specific modem settings such as initialization strings and dial strings must also be specified.

For serial modem operation, you may need to configure the device board's BIOS and jumper settings. See the documentation for the particular device for details.

CAUTION: If you choose to set custom configuration for LAN or serial communication to the BMC, use extreme caution when making changes to the settings. Erroneous settings can disable the device's BMC communication with this product.
