msa1500 serial line check errors

[mesb1]

Hi.

Have msa1500. Serial line nagios machine connected to it. There is only one controller in this setup.

I get new version via:

wget https://raw.github.com/glensc/nagios-plugin-check_raid/master/check_raid.pl -O check_raid.pl

Then:

./check_raid.pl -d -p hp_msa --plugin-option=hp_msa-serial=/dev/ttyS0 --plugin-option=hp_msa-enabled
check_raid Version 3.2.3
See CONTRIBUTING.md how to report bugs with debug data:
https://github.com/glensc/nagios-plugin-check_raid/blob/master/CONTRIBUTING.md

UNKNOWN: hp_msa:[Plugin error]

I look inside and looks like it gave controller few commands:

If you need more checking this part of script i can try find couple free hdd for making test unit like raid1+hot spare.

Checking latest:

./check_raid.pl -d -p hp_msa --plugin-option=hp_msa-serial=/dev/ttyS0 --plugin-option=hp_msa-enabled
check_raid Version 3.2.4
See CONTRIBUTING.md how to report bugs with debug data:
https://github.com/glensc/nagios-plugin-check_raid/blob/master/CONTRIBUTING.md

And no any output. But when i break script and connect via minicom and try put enter, msa say too long command. Looks like there was send something, but maybe wrong way?

I can't see any settings of com port inside script like: 19200 8N1 no hardware flow control no software flow control.

How it can use comport if no any settings for it?

[mesb1]

Did some research: There must be atleast:

my $port = new Device::SerialPort("/dev/ttyS0"); 
$port->user_msg(ON); 
$port->baudrate(19200); 
$port->parity("none"); 
$port->databits(8); 
$port->stopbits(1); 
$port->handshake("xoff"); 
$port->write_settings;
$port->lookclear; 
$port->write("some command to com-port");

my $answer = $port->lookfor;

[glensc]

i'm not sure, but afaik the port settings are "default" if the script does not change them, and "defaults" are set with setserial from rc.serial, or whatever is default by kernel (dmesg |grep ttyS).

so in my script just open /dev/ttyS0 like bidirectional file

[glensc]

so, give Device::SerialPort a try, change in package hp_msa:

my $modem = SerialLine->new($ctldevice, %opts);

with Device::SerialPort use

(I don't have this hardware anymore, nor any hardware to connect with serial port to test this myself)

[mesb1]

Ok, i will try. For now is playing with setserial /dev/ttyS0 baud_base 19200 but not very lucky.

[mesb1]

Well, looks like it's not quite normal doing it via setserial. As example there is parameters for msa like 19200 8N1, we can't set any of them exept base_baud 19200.

For now try some script that is working: use Device::SerialPort; my $port = Device::SerialPort->new("/dev/ttyS0");

$port->baudrate(19200); $port->databits(8); $port->parity("none"); $port->stopbits(1); $port->write("show globals\rshow this_controller\rshow other_controller\rexit\r");

while(1) { my $byte=$port->read(1); print "$byte"; }

But have problems for now with inserting this inside of hp_msa plugin.

P.S. Wasn't trying to look into 4.x.x for now. I'am on 3.2.x version.

[glensc]

so rebase your work on 4.x branch

[glensc]

there was bug parsing commandline options, this has been fixed now:

• fix plugin commandline options support, a2c5b8a
