In our previous article, we discussed about showvv command which is basically used for collecting 3PAR virtual volume information. In this article, we will explore showvlun command which is used for collecting information about VLUNs in the system.
showvlun command, when used along with different options, it will give you all the information you need and you can fine tune it according to your requirement.
Let's see how,
showvlun command when used with -lvw option, it will show the WWN of the virtual volume associated with the VLUN.
when used with -host option, it will show only VLUNs exported to hosts that match with the given host name.
If we want to display VLUNs that are exported to a host set, we should use -host set: followed by the hostset name. we can use comma separated values to include multiple patterns.
for eg: if I want to display the luns which are assigned to one of my ESX server lab01pesx032, I should use,
If I want to display the luns which are assigned to a host set DC_ESX_CL05, I should run below command.
There are options like -v and -t are also available, but generally for reporting and troubleshooting, we will rely on above mentioned options.
