- Additional information
| Auto rearrange |
|---|
Explanation: Auto rearrange is enabled or disabled.
Action: This is an information message. No action is required.
| Controller is not responding to commands. No logical drives are installed. |
|---|
Explanation: The ServeRAID adapter or controller is not operational.
Action: Have the system serviced.
| Error: Cannot disable this adapter BIOS. |
|---|
Explanation: The ServeRAID adapter or controller was unable to prevent an extra copy of its BIOS code from being stored on the server. This condition occurs when the server contains multiple ServeRAID adapters or controllers.
Action: This is an information message. No action is required.
| Following drives found in new location (old ch: old SID: > new ch: new SID) |
|---|
Explanation: Configured drives are not in the configured location. This message will be preceded by the previous messages and the F5 key choice because configured drives were not found in the configured location. When the ServeRAID adapter or controller detects that a previously configured drive is present, but the drive is in a new location, the following message appears:
- old ch is the channel that matches the existing drive configuration information.
- old SID is the SCSI ID that matches the existing drive configuration information.
- new ch is the channel where the drive is now located.
- New SID is the SCSI ID where the drive is now located. For example: (1 :5 > 1: 14) In this example, the message indicates that the drive from Channel 1, SCSI ID 5 is now located at Channel 1, SCSI ID 14. The drive might have been physically moved to the new drive bay.
Action: Press one of the following keys:
| Key: | Explanation: |
|---|---|
| F4 | Retry. Press this key after correcting a problem. For example, press F4 after you move the hard disk drive to its previously assigned location. |
| F5 | Accept. Press this key to accept the new state that the ServeRAID adapter or controller will assign to the drive. For example, the ServeRAID adapter or controller will assign the drive a state of defunct (DDD) or empty. NOTE: A hard disk drive in the DDD state does not necessarily mean that you need to replace the drive. Before you replace the drive, ensure that:
|
| F6 | Modify. Press this key to modify the configuration to match the current drive location. You might remove the hot-swap drives from the server for security or maintenance reasons. If you replace the drives but install them in different drive bays, you can press F6 to accept the new locations, and the ServeRAID adapter or controller will update the configuration. |
| Following drives not responding (old state: new state: ch: SID) |
|---|
Explanation: Configured drives are missing. The ServeRAID adapter or controller has detected that a previously configured drive is missing. One or more drives did not respond to the ServeRAID adapter or controller. For example, the ServeRAID adapter or controller detected a new drive at an unconfigured SCSI ID, and the drive is not part of the current configuration.
- Old state is the configured state of the drive.
- New state is the state that the ServeRAID adapter or controller will assign to the drive.
- ch is the channel where the drive was located previously.
- SID is the SCSI ID for where the drive was located previously
| Status | Description |
|---|---|
| (ONL: DDD x: y) | Online to Defunct |
| (RDY: EMP x: y) | Ready to Empty |
| (SBY: EMP x: y) | Standby to Empty |
| (RBL: DDD x: y) | Rebuild to Defunct |
| (HSP: DHS x: y) | Hot Spare to Defunct |
| (SHS: DHS x: y) | Standby Hot Spare to Defunct |
Action: Press one of the following keys:
- F4 Retry. Press this key after correcting a problem. For example, press F4 after you turn on the external storage enclosure that contains the hard disk drive.
- F5 Accept. Press this key to accept the new state that the ServeRAID adapter or controller will assign to the drive. For example, the ServeRAID adapter or controller will assign the drive a state of defunct (DDD) or empty (EMP). You can also press F5 when you must remove a drive, RAID level-1 and RAID level-5 logical drives are present, and performance in a degraded mode is acceptable. The ServeRAID adapter or controller will assign the drive a state of defunct (DDD), but the server can complete startup. However, the array will remain in Critical mode and the potential for data loss will exist until you replace and rebuild the defunct drive. To prevent the loss of data, replace and rebuild the defunct drive in a timely manner.
- F10 Continue. Press this key to continue without change to the configuration.
Note: A hard disk drive in the DDD state does not necessarily mean that you need to replace the drive.
Before you replace the drive, ensure that: All cables are connected properly to the backplane and to the hard disk drive. Also, ensure that all cables inside the server are connected properly. The hot-swap drive trays are seated properly in the drive bay. If you have not already attempted to rebuild the drive, try rebuilding it. After you perform these steps, if the hard disk drive does not function properly, replace the drive.
| Following new drives found: (host id: old ch: old SID: new ch: new SID) |
|---|
Explanation: This message appears when the ServeRAID adapter or controller detects a new drive that is not part of the current configuration. A new adapter has been installed in a configured server, or drives are imported. This message might be preceded by the previous two messages and the F5 and F6 key choices because the drives were not found in the configured location. When the ServeRAID adapter or controller detects that the identifiers of the drives do not match the adapter configuration information.
- host id identifies the System Name where the ServeRAID adapter or controller resides.
- Old ch is the channel that matches the drive configuration information.
- Old SID is the SCSI ID that matches the drive configuration information.
- New ch is the channel where the drive is now located. New SID is the SCSI ID where the drive is now located. For example, when drivers are imported from a server with the System Name of My Machine: (My Machine: 1:6 > 1:10) In this example, the message indicates that the drive from Channel 1, SCSI ID 6 is now located at Channel 1, SCSI ID 10. The drive might have been physically moved to a new drive bay.
Action: Press one of the following keys:
| Key | Explanation |
|---|---|
| F4 | Retry. Press this key after correcting the problem. For example, press F4 after you move the hard disk drive to its previously assigned location, or after you install the original hard disk drives back in the server. |
| F5 | Accept. Press this key to accept the new state that the ServeRAID adapter or controller will assign to the drive. For example, the ServeRAID adapter or controller will assign the drive a state of defunct (DDD) or empty (EMP). |
| F6 | Modify. This choice is not always active. Press this key to modify the configuration to match the current drive location. You might remove the hot-swap drives from the server for security or maintenance reasons. If you replace the drives but install them in different drive bays, you can press F6 to accept the new locations, and the ServeRAID adapter or controller will update the configuration. |
| F7 | Import. Press this key to import the configuration information from the drive and to update the configuration information for the ServeRAID adapter or controller. This choice is useful when you replace the ServeRAID adapter or controller in an existing ServeRAID subsystem. You also might press F7 if you replace a whole set of drives with drives that were configured in another server with a ServeRAID adapter or controller. Note: A hard disk drive in the DDD state does not necessarily mean that you need to replace the drive. Before you replace the drive, ensure that:
Note: When you install drives in a server that has no logical drives defined, the F7 choice will not appear. The ServeRAID adapter or controller does not contain any logical drives in its factory configuration. Therefore, F7 will not appear. In this case, do the following:
|
| Following new drives found (old state: new state ch: SID) |
|---|
Explanation: One or more drives were found at an unconfigured SCSI ID. For each drive listed, a new state of Ready (RDY) appears.
Action: This is an information message. No action is required.
| Installation stopped. |
|---|
Explanation: The server cannot access the ServeRAID adapter or controller.
Action: This is a follow-on message to a preceding message. Follow the "Action" instructions for the preceding message to resolve the problem.
| n logical drives are installed. |
|---|
Explanation: n represents the number of defined logical drives.
Action: This is an information message. No action is required.
| NVRAM Cache Controller Not Responding |
|---|
Explanation: BIOS code detected a bad or failed NVRAM.
Action: Press F9 to remove the NVRAM cache controller from the configuration, or press F10 to exit without change.
| NVRAM Cache Controller Replacement |
|---|
Explanation: The ServeRAID controller detects that the NVRAM cache controller is defective.
Action: Press F8 if you replaced the NVRAM cache controller, or press F10 if you have not replaced the NVRAM cache controller.
| Recoverable configuration error |
|---|
Explanation: The configuration data stored in NVRAM does not match the configuration data stored in the EEPROM.
Action:
- Press Ctrl+Alt+Del to restart the system.
- Press Ctrl+I when prompted to start the ServeRAID Mini-Configuration Program.
- Select Advanced Functions from the Main Menu.
- Select Import Configuration from Drive(s).
| Warning: n logical drives are critical; n logical drives are offline. |
|---|
Explanation: One or more hard disk drives have failed.
Action: Replace the defunct drives as soon as possible to prevent data loss.
| Your server has an error due to a Blocked Logical Drive. |
|---|
Explanation: One or more logical drives are in a blocked state. A blocked logical drive cannot be accessed.
Action: Press F4 to unblock the logical drive, or press F5 to continue without unblocking.
