Adapter POST and Setup Messages
Adapter Status and Error Messages
Configured Drives Are Not in the Configured Location
The following information contains the &sraid. diagnostic and run-time error messages that might appear during startup of a PC Server disk-array model.
The RAID adapter contains a device-error table that collects statistics on the number and type of errors that occur on a selected hard disk drive. After correcting a problem with the disk array, you should clear the table so that you can identify any subsequent errors quickly. For more information, see'Obtaining Drive Status—.
All hard disk drives contain unique identifiers, such as the drive serial number and manufacturer. During configuration, the RAID adapter stores this information.
The RAID adapter also adds an additional unique identifier, called the host ID, to each hard disk drive that is part of a logical drive. The host ID is a user-defined 12-character string. (See 'Changing the ServeRAID Adapter Parameters— on assigning a host ID.)
Raid Adapter POST and Setup Messages
During POST, the RAID adapter compares the stored configuration information to the configuration that is actually present. If a discrepancy exists, one or more status messages appear after POST completes, but before the operating system loads. When the RAID adapter requires your input, a list of function keys will appear below the message.
New Drive Installed:When the RAID adapter detects a new drive that is not part of the current configuration, the following message appears:
(old state: new state ch: bay)
This is an information message. No action is required.
Configured Drives are Missing:When the RAID adapter detects that a previously configured drive is missing, the following message appears:
old state: new state: ch: bay
where oldstate is the configured state of the drive, new state is the state that the RAID adapter will assign to the drive, chand bay are the channel and bay where the drive was located previously.
Examples of the possible state changes include:
(ONL: DDD x: y)
(RDY: EMP x: y)
(SBY: EMP x: y)
(RBL: DDD x: y)
(HSP: DHS x: y)
(SHS: DHS x: y)
Two choices will follow this message:
F4 Retry. Select this key after correcting a problem. For example, select retry after you turn
on the external storage enclosure that contains the hard disk drive.
F5 Select this key to accept the new state that the RAID adapter will assign to the
drive. For example, the adapter will assign the drive a state of defunct or empty.
You can also select 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 RAID adapter will assign the drive a state of defunct, 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.
Configured Drives Are Not in the Configured Location: When the RAID adapter detects that a previously configured drive is present, but the drive is in a new location, the following message appears:
(old ch: old bay: > new ch: new bay)
where old channel is the channel that matches the existing drive configuration information, old bay is the bay that matches the existing drive configuration information, new ch is the channel where the drive is now located, and new bay is the bay where the drive is now located.
For example:
(1 :6 > 2:14)
(2 :5 > 2: 6)
In this example, the message indicates that the drive from Channel 1, Bay 6 is now located at Channel 2, Bay 14, and the drive from Channel 2, Bay 5 is now located at Channel 2, Bay 6. The drive might have been physically moved to the new bay.
Three choices will follow this message:
F4 Retry. Select this key after correcting a problem. For example, select retry after you move
the hard disk drive to its previously assigned location.
F5 Select this key to accept the new state that the RAID adapter will assign to the drive.
For example, the adapter will assign the drive a state of defunct.
F6 Select this key to modify the configuration to match the current drive location.
You might remove the hot-swap drives from the server for security reasons. If you replace the drives but install them in different bays, you can press F6 to accept the new locations, and the RAID adapter will update the configuration.
New Adapter Installed in a Configured Server
When the RAID adapter detects that the identifiers of the drives do not match the adapter configuration information, the following message appears:
host id: old ch: old bay: new ch:new bay
where host ID is the adapter identification, old channel is the channel that matches the drive configuration information, and old bayis the bay that matches the drive configuration information. New ch is the channel where the drive is now located, and new bay is the bay where the drive is now located.
For example:
(My Machine : 1:6 > 2:10)
In this example, the message indicates that the drive from Channel 1, Bay 6 is now located at Channel 2, Bay 10. The drive might have been physically moved to the new bay.
Two choices will follow this message:
F4 Retry. Select this key after correcting the problem. For example, select retry after you
move the hard disk drive to its previously assigned location, or after you install
the original RAID adapter.
F7 Select this key to import the configuration information from the drive and to update
the configuration information on the RAID adapter. This choice is useful when you
replace the RAID adapter in an existing disk-array model.
You also might select F7 if you replace a whole set of drives with drives that were
configured in another server with a RAID adapter.
Note | |
When you install drives in a server that has no logical drives defined, the F7 choice will not appear. This can occur when you replace the RAID adapter itself. The adapter does not contain any logical drives in its factory |
Where the 'Action— information tells you to start the IBM RAID configuration program, insert the RAID Adapter Option Diskette in the primary diskette drive (usually drive A); then, press Crtl + Alt + Del. The action column also provides general information about the message.
Where mor nappears in these messages, a number will appear in the actual message.
RAID Adapter Message |
Action |
n logical drives are installed. |
n represents the number of defined logical drives. This is an information message. No action is required. |
Controller is not responding to commands. No logical drives are installed. |
The RAID adapter is not operational. Make sure that the adapter is fully seated. If the problem persists, have the system serviced. |
Error: Cannot disable this adapter BIOS. |
The adapter was unable to prevent an extra copy of the adapter BIOS from being stored on the server. This condition occurs when the server contains multiple RAID adapters. When the prompt to disable extra copies of the adapter BIOS appears, type N (No). |
Following drives not responding. (old state: new state ch: bay) |
One or more drives did not respond to the adapter. For example, the adapter detected a new drive in an unconfigured bay, and the drive is not part of the current configuration. Select F5 to accept the new state that the RAID adapter will assign to the drive. For example, the adapter will assign the drive a state of defunct or empty. |
Following new drives found. (old state: new state ch: bay) |
One or more drives were found in an unconfigured bay. For each drive listed, a new state of Ready (RDY) appears. |
Following drives found in new location (old ch: old bay > ch: new bay) |
POST found that the location of one or more drives does not match the stored configuration information. (See 'Configured Drives Are Not in the Configured Location— for more information.) |
Installation stopped. |
The server cannot access the RAID adapter. |
Recoverable configuration error; run Configuration program. |
The configuration data stored on the adapter NVRAM does not match the configuration data stored in the adapter EEPROM. Insert the IBM RAID Adapter Option Diskette; then, press Ctrl+ Alt+ Del to restart the system. Select Advanced Functions and synchronize the adapter configuration. See 'Resetting the Adapter Configuration— on page 15 for more information. |
&sraid. firmware version xx.yy |
This is the version level of the RAID adapter's firmware. This is an information message. No action is required. |
WARNING: n logical drives are critical; n logical drives are offline. |
One or more drives have failed. Replace the defunct drives as soon as possible to prevent data loss. |
The server has an error due to a Blocked Logical Drive. |
One or more logical drives are in a blocked state. Press F4 to unblock the logical drive, or press F5 to continue without any changes. |
