We received the following inquiry about a possible extension for DiskPaths.

One of our clients has a single node Metro Cluster – i.e. a node per page instead of a HA pair. As a result the check is complaining that there are only two instead of 4 available paths. The same problem occurs for a Single Node Cluster (Entry Level System) that only sees one instead of two paths for internal disks.

We suggest adding a switch so that we can configure the number of paths that are OK.

This raises the question on whether or not to implement a switch --paths=1|2|4|8 in DiskPaths. The command could then be typed as follows:

$ ./check_netapp_pro.pl DiskPaths -H filer
# 8 paths would still be the default setting

$ ./check_netapp_pro.pl DiskPaths -H filer --paths=2
# dedicated declaration for a single node Metro Cluster

If you are interested in this future extension, please leave a comment bellow or send us an email: il@netapp-monitoring.info.
