Hi, We have PA Mon monitoring our dev environment. We get it to send disk space issues to Jira, which works most of the time, but occasionally, we get the following error:

Failed to get the free space from \SERVERNAMEX$. The OS reports: The device is not ready. [Err=0x00000015 (21)

It's not a constant issue with specific servers as we do get calls coming through properly from the same servers, which later fail and then work again later on.

Hi nes31234,

The error code is the reason why the PASM service is not able to get the disk data. There are a few error codes that occur just like your explanation where the OS reports the error and then shortly after everything is okay.

We have a registry value that you can edit that will allow you to add this error code and then if the service receives the error code it will rerun the monitor for the next few minutes trying to get the data. You will need to open RegEdit and go to the following key and add the error code to the string of values that are currently there. Each code is separated with a comma so you would need to add ",21" not including the quotes marks. The registry value is called RPC_RETRY_TARGETS and is located in the key below.
