YouTube video description


This video is about troubleshooting IP connection issues (e.g. iSCSI, management, proxy or breakout connections) on FlashArray systems. I also want to show how easy it can be to work with the Pure command line interface (CLI).


All CLI commands build themselves after the pattern:

COMMANDO SUBCOMMANDO ARGUMENT.

pureXXX SUBCOMMANDO --ARGUMENT (where XXX is a placeholder).


Commandos used in the video:

purehelp

purearray (list)

purenetwork (monitor, ping, trace)


The most important CLI commands in my eyes are:


purehelp -h or --help : prints help to the command line.


purearray list --controller : shows both controllers and their status.


purenetwork list : shows all interfaces (no FC!).

purenetwork monitor --error : shows current errors of all interfaces.

purenetwork monitor --error eth18 : shows current errors of interface eth18.

purenetwork monitor --error --total : shows all errors in sum of all interfaces.

purenetwork monitor --interval 5 --repeat 100 : automatically shows/updates the error display every 5 seconds for 100 times.

purenetwork monitor --historical 5h : shows all interface errors of the last 5 hours.


purenetwork ping --interface eth18* 10.100.112.210** : 1x ping from interface eth18 to IP 10.100.112.210.

purenetwork ping --count 10 --interface eth18* 10.100.112.210** : 10x pings from interface eth18 to IP 10.100.112.210.


purenetwork trace --port 3260 --source 10.100.112.200* 10.100.112.210** : shows/checks route/hops from 10.100.112.200 (Pure Ethernet port) to 10.100.112.210 on port 3260/iSCSi.
