HP BL465c G7 : ESXi 4.1 Issues

HP BL465c G7 : ESXi 4.1 Issues

Having just built a new ESXi 4.1 cluster comprised of BL465c G7’s we’ve run into some interesting issues I thought I would share.

Six BL465c G7 servers have been installed in 2 new C7000 G2 enclosures each with 2x Flex-10 Virtual Connect Modules and 2×20-port 8GB Fiber Channel Virtual Connect Modules. Servers are split 3 per-chassis;

In breif the issues are as follows:

  1. PSOD on reboot and random crashes with PSOD
  2. Corrected Memory Error threshold exceeded
  3. Hang on reboot
  4. ILO Duplicate SSL Certificate Serial Number

Exchange 2007 : Room / Resource Mailbox Conflicts and Cancelations Not Processed.

Exchange 2007 : Room / Resource Mailbox Conflicts and Cancellations Not Processed.

I recently came across an issue with the room mailbox configuration on our Exchange 2007 environment. Cancellations were remaining in the calendar and duplicate appointments were being booked at the same time, resulting in the room becoming double-booked.

The issue was that the mailbox ‘AutomateProcessing’ setting was ‘AutoUpdate’ instead of AutoAccept. To resolve this simply execute the following command from the Exchange shell:

Set-MailboxCalendarSettings “MeetingRoomName” -AutomateProcessing:Autoaccept

To extend the booking window use the following command:

Set-MailboxCalendarSettings “MeetingRoomName” -BookingWindowInDays 540

To allow reocurring meetings and cancel conflicts:

Set-MailboxCalendarSettings “MeetingRoomName” -AllowConflicts False
Set-MailboxCalendarSettings “MeetingRoomName” -ConflictPercentageAllowed 25
Set-MailboxCalendarSettings “MeetingRoomName” -MaximumConflictInstances 10

To grant a user full mailbox permissions:

Add-MailboxPermission “MeetingRoomName” -AccessRights FullAccess -Identity “[email protected]

To restrict booking the resource to a particular user/set of users:

Set-MailboxCalendarSettings “MeetingRoomName” -BookInPolicy “[email protected]”,”[email protected]

To allow other users to book the resource, but have their request authorised:

Set-MailboxCalendarSettings “MeetingRoomName” -AllBookInPolicy:$False -AllRequestOutOfPolicy $False -AllRequestInPolicy $True

To configure the delegates that must authorise the request (they will receive a copy of the request):

Set-MailboxCalendarSettings “MeetingRoomName” -ResourceDelegates “[email protected]“,”[email protected]


vCenter VMware VirtualCenter Server WIll Not Stay Started

vCenter VMware VirtualCenter Server WIll Not Stay Started

Installation of vCenter Server succeeds, but services will not stay started. The most recent vpxd log shows the following error:

[2010-10-11 16:51:49.252 03800 error ‘App’] [VpxVmomi] Failed to create WebService socket: class Vmacore::SystemException(An attempt was made to access a socket in a way forbidden by its access permissions. )

[2010-10-11 16:51:49.252 03800 error ‘App’] [VpxdVmomi] Failed to start VMOMI services: An attempt was made to access a socket in a way forbidden by its access permissions.

[2010-10-11 16:51:49.252 03800 info ‘App’] Shutting down VMware VirtualCenter…

In this case McAfee EPO FrameWork Service was using the same port as the vCenter service. This can be verified by stopping the FrameworkService.exe process.

To resolve this issue change the vCenter HTTP/HTTPS Service ports to a port other than 8443/8080.
