naviseccli lun command fails
hi all
Working on a script to get lun info from an old array before configuring a new array and I can get the list of luns using the server -volmap command, then I go after each lun to get details about capacity and uid, etc but for many luns it cannot find them. I don't get it. Attached is just one example. The getlun # command returns all the details about the "missing" luns, but the lun command alone fails with the error "Could not retrieve the specified (lun). The (lun) may not exist. WTH?
Of course I could extract this info by parsing info from other commands but the lun command options make it real easy to get what I need without much trouble.
thanks

The LUN command was added in Flare 30 to support the Virtual Pool. What specific information are you looking for that you can get with the LUN, but not with the getlun?

Yep. Tried that. Tried running the command from both windows and linux, no diff. Of course, my script is already to chug through 100’s of LUNs and right off the bat “fail”.

what happens when you run "naviseccli -h 1.1.1.4 lun -list -l 305". Maybe LUN 305 is not a pool LUN ?

I thought I had that in the attachment, I get the same result. It’s real weird. There doesn’t seem to be anything particular about the LUNs it cannot report on.
naviseccli -h 1.1.1.4 lun -list -l 305
Could not retrieve the specified (lun). The (lun) may not exist
thanks

yep, i see that same thing. How shortsighted of navi developers, so much for consistency.

Ok, I did discover that the common theme here is the –l lun# only works with luns in a pool. It will not work against a traditional lun. The name option fails too against thick luns. Man, I can’t cipher this out of the CLI manual and I can’t imagine why the functionality wouldn’t work against a non-pool lun, but seems to be the case here.
naviseccli -h 1.1.1.4 lun -list -name "LUN 305>maptst01_fence_0"
Could not retrieve the specified (lun). The (lun) may not exist
That sucks

Good (well for confirming). Any developers moderating this forum that care to provide a new and improved (working) version of the command?
Even if they do fix it, guess it's back to the drawing board to extract the bits we want.
thanks dynamox

naviseccli is so old, clumsy ..so little changed in years. You will need to get creative and work with what you got. How about dumping output from naviseccli getall, get a list of all LUN by parsing for "LOGICAL UNIT NUMBER" string, then work against that list of LUNs ?

Yeah, getlun works but it doesn’t have the details I’m looking for to script around. I haven’t used the arayconfig command at all but may look into it. It’s really a drag to know that the lun command has exactly what I need but in our case, fails 50% of the time.
thanks

Does the old "getlun" still work for traditional LUNs>
What about the arrayconfig command?

Yeah, the getlun has most but what I was looking for was the thin provisioning aspects of some luns without having to jump between commands. It would seem to me that the lun command would be ideal if only it worked for all types of luns. The getlun is "getting me by" for now.
thanks Glen
