NAME

rmparams - RAID Manager parameter file

DESCRIPTION

rmparams holds runtime parameters for the RAID Manager applications. The applications access these values via internal "get" and "put" interfaces. This scheme provides some control over the RAID Manager behavior without use of command line options or recompilation. The default location is /etc/raid/rmparams.

PARAMETER EXPLANATIONS

NOTE: This man page only documents parameters that are considered safe for users to modify. All other parameters should be left alone.

Monitor_PollInterval

This value is the time in minutes that arraymon daemon will sleep between successive scans of the attached arrays looking for abnormal events. The default value is 5 minutes. The range of acceptable values is 1 to 1440 (24 hours).

Monitor_ParityTime

This value is the time of day that the arraymon daemon will launch the parity check utility if enabled. The value is in the form hh:mm where hh is 0 to 23 and mm is 0 to 59. This utility should be run when system activity will be least impacted. The default time is 02:00 (2:00am).

Monitor_PchkEnabled

This value is tested by the arraymon daemon and if found 1 (enabled), the parity check utility is launched at the appropriate time. If the value is 0 (disabled), the parity check utility is not launched. The default value is 1 (enabled).

Parity_Amount

This value is the number of logical blocks that the parity check utility will scan before pausing for the amount of time specified by the Parity_Delay parameter. This parameter affects both automatic parity (if the Monitor_PchkEnabled parameter is 1 (enabled)) and manual parity. The default value is 10000 blocks. The range of acceptable values is 1000 to 37767 blocks.

Parity_Delay

This value is the amount of time in seconds that the parity check utility will pause for system I/O operations to take place. This parameter affects both automatic parity (if the Monitor_PchkEnabled parameter is 1 (enabled)) and manual parity. The default value is 1 second. The range of acceptable values is 0 to 10 seconds.

System_MaxControllers

This parameter is used by the identification module to dynamically allocate a memory structure to hold data describing each array controller found. The default value is 32. If more controllers are found than what the System_MaxControllers value is defined as, a message will be displayed on the system console noting that the utility will only keep

track of the first x number of controllers.

System_MaxHostAdapters

This parameter, along with System_MaxSCSIid and

System_MaxLunsPerController, is used by the identification module to size a map for all existing device nodes. The max host adapters parameter itself specifies the largest c (controller) number found for all /dev/rdsk/cXtXdXsX nodes, plus one. The default value is 32.

System_MaxSCSIid

This parameter specifies the largest SCSI target ID, or largest number found for all /dev/rdsk/cXtXdXsX nodes. The default value is 31.

System_Max_LunsPerController

The disk array controller is capable of configuring up to 32 individual logical units (LUNs) per controller. The actual number of LUNs supported by an operating system varies. This parameter should be set to reflect the actual number of LUNs the OS supports. The default value is 8.

System_MaxLunsPerHostAdapter

This parameter is a decimal number that informs RAID Manager how many SCSI logical units may be accessed through a single host adapter. RAID Manager uses this information to determine in advance if it will be possible to create and register a new logical unit. Different operating systems or their releases will vary in what this parameter is allowed to be. The default value is 16.

System_CatalogLanguage

The core modules of the RAID Manager package have been internationalized by the use of a message catalog. The System_CatalogLanguage parameter corresponds to the set ID in the RAID Manager message catalog ( /etc/raid/messages.cat ). Supporting a new language involves adding a new set to the messages.txt file and building a new

messages.cat file with the command 'gencat messages.cat messages.txt'. The new language is selected by setting the System_CatalogLanguage parameter to the new set ID. The currently defined sets are:

Set ID

Language

101

ENGLISH

The RAID Manager reserves sets 101 and above for its use. Sets 1-100 are available for user customization.

Notify_LogName

The name of the file where RAID Monitor notification places event entries.

Notify_LogEnabled

"1" if notification logging is enabled, "0" otherwise.

System_SafePassThroughLun

This parameter is a decimal number that specifies a particular logical unit to reserve for RAID Manager's use (in particular, this is the LUN that RAID Manager will use to send SCSI commands directly to drives in the array). Required if the controller software is earlier than 2.03. The specified LUN must exist and must not be used by any application other than RAID Manager.

Rdac_SupportDisabled

This parameter has two values, TRUE or FALSE. TRUE means the RDAC driver and daemons are not to be loaded when the system boots. FALSE (the default and assumed value if parameter is not present) means full RDAC support is enabled. When changing this parameter, perform a reconfiguration boot (boot -r) in order for the change to take effect.

SNMP_Target_IP_Address

This parameter specifies the IP address of the host that is to receive the SNMP traps sent by RAID Manager. This would normally be the IP address of the network management station. If this line is deleted(or commented out by placing a "#" character in the first position of the line), sending SNMP traps is disabled. The default value for this parameter is 127.0.0.1(loopback address).

SNMP_Community_Name

This parameter is the name of the SNMP community. The default value is "NONE". To enable SNMP traps, this parameter should be set to "public".

Viewer_LogSize

This parameter is a decimal number specifying the size in kilobytes that the RAID Manager message log file may grow to before "threshold reached" messages are displayed on application startup. The default value is 40.
