Testing VMkernel network connectivity using vmkping

As we all know vmkernel adapters are critical when working with storage and  vmotion networks. Normally these networks are isolated from each other. So we can not rely only with the “ping” command. In that case, we should be able to ping from the specific adapter (ex: if storage related, need to use the specified vmkernel adapter [vmkX] to ping the storage system).

Will look at the steps,

Step 01 : SSH into the esxi host.

Step 02 : Identify the correct/relevant vmk, that has been mapped/assigned.

Step 03: Run the command in this format [vmkping -I vmkX x.x.x.x]

vmkX is denoted by the vmkernel adapter number / x.x.x.x is denoted by the destination IP address.

Online resources to create Cron Jobs

Creating or editing Crontabs is never easy. A single incorrect value can destroy the entire schedule task. So to prevent such disasters it is always advisable to cross verify the configuration against multiple resources. The below is a list of URLs that you can rely on.
