VMware vSphere PowerCLI is missing cmdlets to work with VMware vCenter Scheduled Tasks. In a series of blog posts I will show you some PowerShell advanced functions that you can use to work with vCenter Scheduled Tasks. The first function is Get-VCScheduledTask. You can use this function to retrieve one or more scheduled tasks from your vCenter Server. Read more of this post

In vSphere 5 a virtual machine can have a “Virtual machine disks consolidation is needed” Configuration Issue warning in the Summary tab.

Last week there was a question in the VMware VMTN Communities VMware vSphere PowerCLI forum from Papires who asked how you can convert the ESXCLI command ‘esxcli storage vmfs snapshot mount -l “DATASTORE”‘ into a PowerCLI command. I had not done very much with ESXCLI in PowerCLI, but I knew that it was something like ‘$esxcli.storage.vmfs.snapshot.mount’. However I was struggling with the ‘-l “DATASTORE”‘ part.
There is not much documentation available about the ESXCLI commands in PowerCLI. And also a search in Google did not help me very much. Finally I found the right answer using the PowerShell Get-Member cmdlet. Read more of this post

Recently we get vSphere alarms in our environment that say for instance:
“[VMware vCenter – Alarm Host error] Issue detected on host in datastore: ScsiDeviceIO: 2368: Failed write command to write-quiesced partition naa.600a0b8000111155000021c53f97784e:1 (42:01:04:07.994 cpu7:5191)”
There seems to be a problem on a partition. But which datastore is on this partition? We can use PowerCLI to find the datastore involved. Read more of this post

For our Boot From SAN servers we wanted to know the SCSI Lun number of the disks. You can get this information via WMI. But to retrieve it you need four different WMI objects. I made a PowerShell advanced function that combines these four WMI objects to relate the disk with the LUN number. Read more of this post

This week VMware announced the vExperts for 2012 and I am proud to be one of them. Last year I didn’t make it. But this morning I received the following e-mail from Alex Maier who is the VMware vExpert Program Manager:
I am pleased to inform you that you have been designated a vExpert 2012 in recognition of your contribution to the VMware, virtualization, and cloud computing community.
You’ve done work above and beyond, helping others succeed with VMware, and we here in the Social Media and Communities team are delighted to welcome you to the program.
VMware vExperts are a special group, a network of peers, who communicate with each other and VMware closely, share resources, and get other opportunities for greater interaction throughout the year.
Thanks for all you do. The vExpert Program is going to be great this year. Keep on rocking!
With kind regards,
Alex Maier (vExpert Program Manager) and the VMware Social Media and Communities Team
Many thanks to Alex and John Mark Troyer, who started the vExpert program three years ago.
I am proud to be part of the VMware vExperts. And I look forward to work with VMware and the other vExperts more closely.
Congratulations to all the other vExperts 2012!
More information about the VMware vExpert program can be found at the vExpert Directory.
