AIX Version 4.3 Commands Reference, Volume 4

nim Command

Purpose

Performs operations on Network Installation Management (NIM) objects.

Syntax

nim {-o Operation} [ -F ] [ -t Type ] [ -a Attribute=Value . . . ] {ObjectName}

Description

The nim command performs an operation on a NIM object. The type of operation performed is dependent on the type of object specified by the ObjectName parameter. Possible operations include initializing environments and managing resources. You can use the lsnim command to display the list of supported operations.

Flags

-a Attribute = Value . . .	Assigns the specified value to the specified attribute. Use the lsnim -q Operation -t Type command to get a list of valid attributes for a specific operation.
-F	Overrides some safety checks.
-o Operation	Specifies an operation to perform on a NIM object. The possible operations are: allocate Allocates a resource for use. bos_inst Performs a BOS installation. change Changes an object's attributes. check Checks the status of a NIM object. cust Performs software customization. deallocate Deallocates a resource. define Defines an object. diag Enables a machine to boot a diagnostic image. dkls_init Initializes a diskless machine's environment. dtls_init Initializes a dataless machine's environment. fix_query Lists the fix information for a given APAR or keyword. lppchk Verifies installed filesets on NIM machines and SPOTs lslpp Lists licensed program information about an object. maint Performs software maintenance. remove Removes an object. reset Resets an object's NIM state. sync_roots Synchronizes root directories for diskless and dataless clients for a specific Shared Product Object Tree (SPOT). unconfig Unconfigures the NIM master fileset. AIX Version 4.2 or later Examples: maint_boot Enables a machine to boot in maintenance mode. showlog Displays a NIM client's installation, boot or customization log, or a SPOT's installation log from the NIM master. showres Displays the contents of a NIM resource. Use the lsnim -POt Type command to get a list of the valid operations for a specific type. AIX Version 4.3 or later Operations: alt_disk_install Performs an alternate disk installation.
-t Type	Specifies the type of the NIM object for define operations. The possible types are: resource types: bosinst_data Config file used during base system installation. dump Parent directory for client dump files. fix_bundle Fix (keyword) input file for the cust or fix_query operation. home Parent directory for client /home directories. image_data Config file used during base system installation. installp_bundle Installp bundle file. lpp_source Source device for optional product images. mksysb AIX mksysb image. paging Parent directory for client paging files. root Parent directory for client / (root) directories. script Executable file which is run on a client. shared_home /home directory shared by clients. spot Shared Product Object Tree (SPOT) - equivalent to /usr file system. tmp Parent directory for client /tmp directories.
