Detailed Description

In situations where nicknames simply are not present, but we need descriptors in short-order, the "--wwn=" or "-w" ooption can be used to get a description of what the most likely Nickname would be.

For example, "java -jar wwndesc.jar -w 5006048ACCC86A32" results in "Symm-182500953-05bA" matching http://www.emcstorageinfo.com/2007/08/how-to-decode-symmetrix-world-wide.html Note that –briefestimate and –nobriefestimate configure for more brief estimate/suggested nicknames

Examples

java -jar vict.jar –wwn 500610601234567

java -jar vict.jar –briefestimate –wwn 500610601234567

java -jar vict.jar –nobriefestimate –wwn 5000097301234564

WWNDesc getWWNDescriptor ( String val )

inline

Iterates WWNDescription decendents looking for which will accept responsibility, and if so, returns the instance it generates as a descriptor.

Returns: new instance of WWNDesc descendent, or null if no descendents accept responsibility to describe or provide an alias for that WWN

Parameters

val	WWN to check

WWNDesc getWWNDescriptor	(	String	val,
		boolean	provideBase
	)

inline

Iterates WWNDescription decendents looking for which will accept responsibility, and if so, returns the instance it generates as a descriptor.

Returns: new instance of WWNDesc descendent, or null if no descendents accept responsibility to describe or provide an alias for that WWN

Parameters

val	WWN to check
provideBase	whether to provide a bogus WWNDesc instance rather than a null

static void main ( String args[] )

inlinestatic

Main function, as you can tell.

this function merely parses the command-line to dispatch actions to the meat of the meal above. I'm using an actual GetOpt because, yes, I'm a UNIX/C hack, re-using 3-decades-old knowledge, but this also preserves both extensibility and the ability to use longopts in scripts as a way to self-document what the tool's doing.

No real intelligence herein except the parse-and-redirect action.

Parameters

args	commandline arguments passed in by the JRE

Always always ALWAYS provide a quick reference and a version output

Commandline Options:: -H|–help Show a simple help screen as a reminder of options which are understood by the application

Commandline Options:: java -jar wwndesc.jar --help

Commandline Options:: -V|–version Show the current release version for reference

Commandline Options:: java -jar wwndesc.jar --version

1.0-76

Commandline Options:: –briefestimate change to shorter, more brief estimates or descriptions

Commandline Options:: –nobriefestimate change to longer, more detailed estimates (default)

Commandline Options:: -d|–device(=) used mainly in testing, this option allows setting a device type

Commandline Options:: { init(iator) | server | storage | switch | targ(et) }

Commandline Options:: -p|–port used mainly in testing, this option shows the port-uniqueness of a device (which can be leveraged for de-duping an alias)

Commandline Options:: -w|–wwn query for a description of a WWPN

Commandline Options:: java -jar wwndesc.jar --wwn 5000097201234567

VMax-HK194618641-10fD

Commandline Options:: java -jar wwndesc.jar --briefestimate --wwn 5000097201234567

void usage ( String proc )

usage messages are useful to those of us with short memories as well (hey, I just need to add swap!)

Parameters

proc	name of the process or program (ie wwndesc)

boolean briefWWNEstimate = false

setting to "true" via the "--briefestimate" commandline causes all descriptions later requested in getWWNDescriptor(String) to be "brief" (more concise)
