cciss_vol_status exclude /dev/sg2

[PitoneMaledetto]

Hi there I am running the plugin with -p cciss
I get this:
Remote command execution failed: cciss_vol_status: open /dev/sg2: No such file or directory

How can I exclude the missing directory, is there a switch to do so?

If I manually run on the server:
sudo /usr/bin/cciss_vol_status -V /dev/sg0 /dev/sg1

I get everything I need.
Thanks

[PitoneMaledetto]

Proposed solution:
A switch for the use of the cciss plugin in order to specify the number of sg# directories to check or to avoid non existent ones.

[glensc]

i was rather thinking iterate over /dev/sgX nodes and skip ones that doesn't exist.

[glensc]

i suppose you don't have lsscsi program installed? and if you do, show lsscsi -g and it's version lsscsi --version

I don't have lsscsi installed. What information are you after?

[PitoneMaledetto]

Iterate seems a good way of solving the non-existent sgX

[glensc]

lsscsi tool is used to detect devices more reliably. try it.

[glensc]

also include command whose output you pasted in those ls -l pastes, to see what path you did ls on

[PitoneMaledetto]

First run:
ls -rtl /dev/disk/by-id/
Second run:
ls -ld /sys/block/sd*/device

[glensc]

edited your post. hopefully correctly.

i'm waiting for you to try installing lsscsi tool and see does the plugin work more as expected with the tool present.
