How to Remove a Storage Repository from XenServer

This article describes how to remove a Storage Repository (SR) on a XenServer host when the Storage Repository is experiencing issues, or if you wish to discontinue using the Storage Repository.

A XenServer Storage Repository is used to Store ISOs or Virtual Machine (VM) Virtual Disks (VDIs). The Storage Repository is connected to a XenServer through a Physical Block Device (PBD) which contains the configuration for the Storage Repository. It is necessary to disconnect the PBD before you detach or remove the Storage Repository from the XenServer host.


PGP Command LIne – Licencing on VmWare Metro hosts

I do not need a solution (just sharing information)

We are looking to move our PGP command line from a physical server onto a VM that is hosted on VMMare  Metro Clustering. Are there still licence implications if the host was to move from one ESX Host to another ? We don’t want to go down route of setting affinity rules to tie to one particular ESX host.



NetScaler Error: ad0: FAILURE – SETFEATURES ENABLE WCACHE status=51 error=0

The resolution would be to FRU underneath hyper V HDD or to move VM to different HYPER-V

If you still see same HDD errors “ad0: FAILURE – SETFEATURES ENABLE WCACHE status=51 “, “ad0: TIMEOUT – WRITE_DMA retrying “ and then vmcore, then move the NetScaler VM to a different disk.
