If there are issues getting the remotely installed plugin installed in Pure's VMware appliance or the locally installed plugin installed onto your vCenter, it's a great idea to check the virgo logs. There might see something like the below:
DOWNLOAD_FAILED: Error downloading plugin package com.purestorage.purestoragehtml:4.2.0 from https://ArrayManagementIPAddress/download/purestorage-vsphere-plugin.zip?version=4.2.0. Reason: Download error. Make sure that the URL is reachable and the thumbprint is correct. java.net.SocketTimeoutException: connect timed out
This log line often means there is a communication issue between wherever the plugin is being downloaded from (for the remote plugin, Pure1 or the OVA attached to the VM; for the local plugin, the array or where the PowerShell files are hosted) and going to the vCenter.
Resolution:
For the remote plugin, port 443 needs to be opened up between Pure's VMware appliance's network interface and the Pure1 cloud and additionally between the vCenter's management interface and Pure's VMware appliance's network interface. For the locally installed plugin, if installing with PowerShell, you'll need to open up 443 between the vCenter's management interface and pure-vmware-plugin-repository.s3-us-west-1.amazonaws.com; if installing from the array, you'll need to open up 443 between the vCenter's management interface and the array's management IP addresses.
