Novell Linux Volume Manager can be used to manage NSS file systems or Linux POSIX file systems on your OES server. This section describes the general syntax and conventions for NLVM.
Using commands for the NLVM program requires root user privileges. NLVM options must follow immediately after nlvm.
nlvm [nlvm_options] <command> <command_options>
When issuing NLVM commands, consider the following general syntax conventions:
All NSS pool names and NSS volume names are automatically converted to uppercase.
NSS software RAID names are case sensitive.
When you create an NCP volume, the name is automatically converted to uppercase.
Command options can be specified in any order except where it is otherwise noted. Options with an equal sign (=) can be in any order.
All sizes are in bytes and can be specified with one of the following multipliers: K, M, G, and T. Multipliers are case insensitive and are multiples of 1024. If no multiplier is specified, it is assumed to be G by default. If ‘max’ is entered, all of the free unpartitioned space on the device is used. All sizes can be entered as whole numbers or with fractional parts such as 200.45G and 3.98T.
Examples for common command options:
size=20 (If no multiplier is used, it is assumed to be G (gigabytes).)
size=20G (You can also specify max instead of a value and multiplier.)
size=3.98T (You can specify a value with decimal places.)
Examples for common name formats used in command options:
device=sdb (You can specify the leaf node name of the device, including multipath names.)
device=/dev/mapper/mpatha (You can specify the full Linux path of the device.)
device=anydisk (You can specify anydisk or anyshared keywords if the command allows it.)
part=sdc1.1 (You can specify only the partition node name, not the full Linux path.)
part=cluster1.sbd
name=MYPOOL1 (All NSS pool names and NSS volume names are converted to uppercase.)
In the command syntax for NLVM, the mandatory command options are surrounded by angle brackets (<>). The optional command options are surrounded by square brackets ([]). The brackets are not used when you issue the command. For example, the command syntax conventions are:
nlvm [nlvm_options] command <mandatory_value> [options]
The following are key files used by NLVM:
Location of the NLVM configuration file.
Location of the NLVM utility. It also has a link in the sbin directory so that it is in the search path.
Location of the debug log files.
