vCloud Director not reporting CPU Utilization

I came across a customer site recently where their vCloud Director (vCD) 5.1 implementation was not reporting CPU utilization for Organisation Virtual Datacenters (Org VDCs). RAM and storage allocation was fine, just CPU was not showing a usage bar, and the mouse over tip reported 0% allocated. Turns out this is a known issue with vCloud Director 5.1, and VMware have released KB 2054043 relating to this issue. Their advice (via the KB) is to: Upgrade vCloud Director to version 5.1.2 or later. Enable Elastic Allocation Pool mode for vCloud Director. To do this: Login to vCD as a System Administrator user. Navigate to Home > Administration > General. Unter the Miscellaneous section, check the box next to 'Make … [Read more...]

vCAC 6.0.1, Inaccessible Tenants, and Missing Identity Stores

With vCAC 6.0.x, there is a bug in the SSO appliance where several symptoms present all at the same time: Authentication to AD or LDAP identity stores fails, returning the user to the blank authentication screen. When logged-in to the default tenant as administrator (usually 'administrator@vsphere.local'), accessing tenant identity stores results in a 'System Exception' error. Tenant Admins cannot add or edit identity stores. This is a documented bug, as listed in VMware KB Article 2075011, and at the time of writing there is a workaround. The issue as documented is the administrator account in the default tenant expires 90 days after implementation of the appliance. I came across this issue, and was for a while not … [Read more...]

Public Catalog Access for vApp Authors fails post-v5.5.1 Upgrade

vAppAuthor

This one stumped me for a little bit. The private cloud in my lab is fairly simple in layout - 2 RHEL cells with a vCNS load balancer, shared NFS server and DB server. The Organisations are provisioned such that of the 3 tenants, one is a master tenant that is only used for creating and maintaining vApp templates, via a Public Catalog for sharing the templates for cloud provisioning and vCAC blueprint testing. Running this configuration in with no changes to the default vCloud Director (vCD) roles worked fine - delegated LDAP users in the 2 user organisations were able to select vApp templates from the Public Catalog and deploy them locally. All good. The issue came when the cells for vCD were upgraded to the latest v5.5.1 build. … [Read more...]

Concept Explained: Running Multiple vSphere Replication Appliances

vSR-Concept

Playing with vSphere Replication in my lab recently (following my joyous experiences with my HP MSA P2000 detailed here), I came across a small gotcha that might catch out some of those who (like me) learn stuff by playing with them, whilst reading about the deployment technical aspects alongside. vSphere Replication in vSphere 5.5 has been enhanced over the v5.0/1 release, to enable multiple replication appliances to be deployed and managed by the same vCenter instance. vSphere 5.5 allows upto 10 replication appliances per vCenter, selectable on configuring a VM for replication or available for auto-selection. The gotcha comes when registering subsequent appliances to a vCenter after initial replication connection has been … [Read more...]

HP P2000, Controller Crashes & ESXi PSOD!

I've recently been dealing with an interesting issue in my lab, as a result of deciding to upgrade the entire infrastructure to vSphere 5.5GA from vSphere 5.1. I'm lucky to have a pair of HP MSA P2000 units in my lab, connected to (amongst other boxes) some HP hosts - these items are the focus of this post. The MSAs and hosts were in the configuration as follows: MSAs paired over L2 network, each connected to a different /24 network. No QoS applied to either network. Hardware fully patched to the latest HP revisions. MSAs paired together using HP RemoteSnap replication software (for testing VMware Site Recovery Manager). Snapshots taken and replicated from 'primary' to 'secondary' every 30 minutes. Single vDisk defined per … [Read more...]

Improving vSphere Web Client Performance

flashwebsettings

With the release of the (now maturing) VMware vSphere 5.5 release, more and more operations (but not all - yet) are being migrated to the vSphere Web Client. Functionality of the vSphere 5.1 features are all fully available in the vSphere 5.5 .Net Windows client (the traditional client) along with Site Recovery Manager and Update Manager administration functions, but any and new vSphere 5.5 features are now only available via the web client. Lots is made of the performance of the web client, and having used it on my home lab and now in Production environments, I can see why some users report on there being some perceived performance lag in the web client compared to the Windows client (population of menus, general navigation etc). … [Read more...]

vCloud Director 5.1 to 5.5 Cell Upgrade ‘cpio: chown failed’

vcd5.5cellupgrade

Upgrading my lab environment from vCloud Director v5.1 to v5.5, I came across an interesting error whilst upgrading the cells. My lab has the following vCD configuration: 2 x RHEL 6.2 Cells 1 x RHEL 6.2 NFS Server 2 x vShield load balancer instances 1 x Windows 2008 R2 DB server running SQL Server 2005 The upgrade process was: Quiesce the cell using the Cell Management Tool commands. (Upgrade Guide) Upload the vCD .BIN file to the /install directory of the cell (using WinSCP or similar). Change the execution parameters for the vCD .BIN file. (Upgrade Guide) Running the installation .BIN file. (Upgrade Guide) Confirm the existing v5.1 cell instance can be upgraded. This is where the interesting error came in. The … [Read more...]

Getting Started with VMware Certification (The Easier Way)

It's always been difficult to justify getting started on the journey to a VMware certification. In the past, the first certification available from VMware was the VMware Certified Professional (VCP). This in itself was a large first step to take, comprising an instructor-led prerequisite and a technical-level exam. Somewhat daunting and costly! All that is changing with 2 important new developments from the VMware Certification Team: VMware Certified Associate (VCA) and on-line training availability. The VMware Certified Associate-level exams are aimed at giving users a broader understanding of the 4 technology areas (Virtualization, Cloud, Mobility & Network Virtualization), to allow them to become conversant in the technologies … [Read more...]
