NAME

arraylog — accesses and clears disk array logs

SYNOPSIS

arraylog [-u] [-e] [ -d slot [-p pagecode] ] [ -C { -c | -d slot} ] [-?] array-id

DESCRIPTION

arraylog provides access to the controller and disk logs maintained by the disk array identified by array-id. These logs contain information useful for diagnosing and troubleshooting the disk array. The logs can also be cleared using arraylog.

The array-id used to address the disk array can be the disk array serial number, the character device file name of any LUN on the array (LUN 0 if no LUNs are created), or the alias text string assigned to the disk array.

Options

arraylog supports the following options:

-C { -c | -d slot }

Clear the specified logs. If -c is specified, clear the disk array controller usage and event logs. Both logs will be cleared when using this option. It is not possible to clear just one of the logs.

If -d is specified, clear the log for the disk installed in the cabinet slot identified by slot.

-d slot [-p pagecode]

Display the contents of the log for the disk installed in the cabinet slot identified by slot. Slot numbers must be of the form An or Bn, where A or B correspond to a cabinet column, and n corresponds to a shelf position (1-6).

The -p option returns the log information identified by pagecode. The use of the -p option is intended primarily for accessing logs on unsupported disks.

-e

Display the contents of the disk array controller event log.

-u

Display the contents of the disk array controller usage log.

-?

Display expanded usage message. This option overrides all others.

EXTERNAL INFLUENCES

Environment Variables

LC_MESSAGES determines the language in which messages are displayed. The current language settings can be checked with locale(1).

RETURN VALUE

arraylog returns the following values:

0: Successful completion.
1: An error in execution (I/O, subsystem, security, etc.) occurred.
2: An error in command syntax occurred: for example, an unknown command-line option was passed.
3: Timeout in communication to server. May indicate ARMServer is not running.

DIAGNOSTICS

The following messages can be generated by arraylog:

Usage: arraylog {[-u] [-e] [-d n [-p n]] [-C -c] [-C -d n]} [-?] 
<array-id> 

An error in command syntax has occurred. Re-enter the command with all necessary arguments.

arraylog: Arg out of range

One of the arguments has exceeded its maximum or minimum size, or is incorrect in form. Check the size and form of each argument.

arraylog: No such file or directory

The specified array-id does not exist or does not identify a disk array that is communicating with the system. Verify the correct array-id with ioscan(1M) or arraydsp(1M).

arraylog: Unknown argument

An invalid argument was specified. Check command usage.

arraylog: Error in command execution, <Additional Error Info>: 
<Error Info Decode> 

The command failed due to a device error, an internal error, or a system error. The Additional Error Info and Error Info Decode fields will hold specifics about the failure and its cause.

arraylog: Cannot clear logs on an unsupported disk.

An attempt was made to clear the logs on an unsupported disk. The logs on an unsupported disk cannot be cleared using this command.

arraylog: No disk in slot n.

There is no disk in the indicated slot.

Use the -p [pagecode] option to attempt to recover any log information. 
Any recoverable log data will be displayed as a hex dump. 

The logs on an unsupported disk cannot be interpreted by the arraylog utility. Using the -p [ pagecode ] option will cause the utility to retrieve any log information it can from the disk.

arraylog: Array was just powered-on or reset.

The command failed because the disk array has been powered-on or reset. Reissue the command and it should succeed.

EXAMPLES

Display the controller usage log for the disk array identified by device file /dev/rdsk/c2t0d0:

arraylog -u /dev/rdsk/c2t0d0 

Display the controller event log for disk array serial number 00786b5c0000:

arraylog -e 00786b5c0000 

Display the log information for the disk installed in slot A2 of the disk array identified by device file /dev/rdsk/c2t0d0:

arraylog -d A2 /dev/rdsk/c2t0d0 

Clear the controller event and usage logs for disk array serial number 00786b5c0000:

arraylog -C -c 00786b5c0000 

Clear the log for the disk installed in slot B1 of disk array serial number 00786b5c0000:

arraylog -C -d B1 00786b5c0000 

DEPENDENCIES

ARMServer must be running to execute this command. See ARMServer(1M).

SECURITY CONFIGURATION

This command is modified for all security configurations.

Security Behavior/Restrictions

Use of this command is restricted to authorized users only.

Command Authorizations

This command requires the sysadmin authorization to successfully execute.

Privileges

The command has been modified to support least privilege. The potential privileges possessed by the command and their uses include:

allowdacread: This privilege is raised to provide discretionary read access to the devices.
allowdacwrite: This privilege is raised to provide discretionary write access to the devices.
allowmacread: This privilege is raised to provide mandatory read access to the devices.
allowmacwrite: This privilege is raised to provide mandatory write access to the devices.
filesysops: This privilege is raised to allow the mknod(2) system call to succeed.
writeaudit: The command generates its own audit records and submits these directly to the system audit trail. This privilege is raised whenever the command needs to write an audit record.
