Ran in to an issue before Christmas whereby ESXi would take over 10 minutes to boot. The issue appeared to be with regards to certain LUNs timing out during the rescan operation.
Upon further investigation, the LUNs causing the issue were RDMs connected to a MSCS cluster. The workaround for this was to set the Scsi.UWConflictRetries from 1000 (default) to 80. Whilst this shortens the boot time, it’s still relatively long and really worrying when utilising DPM.
KB1016106 covers this topic in full.

I’ve been running a proof of concept lately with View 4.0 and Windows 7 and have had a constant showstopper issue (experimental… I know!).
Using PCoIP, 80% of the time when the end user logs in they will be greeted by a black screen for a couple of seconds and then the session will quit. Logging back in works as normal.
Looking at the View 4.0 release notes there are a few mentions of black screens but only one relevant to Windows 7:
When View Client attempts to connect to a Windows 7 desktop using PCoIP, a blank black screen will appear instead of the Windows Security dialog box if the Windows 7 desktop fails to perform single sign-on, for example, if the desktop does not join the domain.
At first, I thought this issue may have been one with my template and not deploying properly through Composer, but after testing through the console this was quickly ruled out.
With the release of View 4.0.1 comes a rather interesting KB (KB1016961) from VMware.
This KB refers to the same SSO issues mentioned above but this time indicates that a legal disclaimer can trip up the SSO process! The workaround is to disable any disclaimers.
Definitely one that will trip up a few POCs up in the early stages I feel.

Due to feeling a bit rough last week and being very busy the week before I have failed miserably in my attempt to update the blog.
Good news though, currently running parallel View/XenDesktop POCs (including XenApp/ThinApp/App-V application virt), doing yet another CX4 upgrade (YACXU), rolling out a load of new ESX clusters, adding a shed load of spinning disk thingies, EMC Recoverpoint and some top secret ‘things’ so lots to write about.
Also have part written posts on EMC Replication Manager, the impact of MV/A (and thus SRM) on performance and something quick on ESXi scripted installs – although I think I may have been pipped to the post on this one.
And finally, passed my VCP4 last Friday with a score of 458/500 from memory. Next up is completing my CCNP before they update it.
