How to test the alerting in a Pure Storage FlashArray

When configuring SMTP or syslog for alerting the easiest way to configure is in the GUI, simply because everything you need to configure is right there in plain sight.

For this example, we will assume the syslog servers and SMTP relay host and sender domain have been specified. If not, these can be set from the GUI under Settings > System > Syslog servers and Settings > System > Alert Routing.

But to test if it all works is a different story: there’s no test button!

So we need to log on to the CLI. Use your favorite SSH client and log on the the array.

Syslog

First you can view if the syslog was configured according to your liking by entering the command:

purelog list

You should now see the configured syslog servers and the ports that are used.

To test if syslogging works enter the command:

purelog test

SMTP

For emails the command to view the settings is:

purealert watcher list

You should now see the email addresses that will be used whenever the array needs to send an email. To test this you need to use the following command:

purealert watcher test [email protected]

If all goes well you will then receive an email similar to:

Hello,

This is a test message from your Pure Storage Array.

Troubleshooting error-disabled issues between a Cisco UCS fabric interconnect and a Cisco MDS

Cisco MDS

When connecting a high speed cisco UCS Fabric Interconnect (like the 6454) to Cisco MDS Fibre Channel switches, you might encounter error-disabled ports causing the port-channel to go down. Specifically for 8 Gbps speeds you need to enter 1 additional command per port that’s participating in the port-channel:

int fc1/17
switchport fill-pattern IDLE speed 8000

For each fc port on the MDS you need to enter this command, followed by a “shut / no shut” and the error disabled problems are most likely gone.

Check to see the port config:

show run int fc1/17

Or whatever port you configured to use the fill-pattern.

How to upgrade a Cisco MDS SAN switch

Cisco MDS

After a few years of not having had to perform switch upgrades, I had to perform a few firmware upgrades on MDS switches. I decided to write down the steps I had to take:

  • First make sure you have a reachable ftp server somewhere and write down its ip address
  • Log on to the Cisco MDS SAN switch you need to upgrade
  • Make sure the bootflash: has enough available space to hold the 2 new files

# dir bootflash:
