VMware: The datastore “name” is connected to one or more pre-4.1 hosts that do not support Storage I/O Control

October 23rd, 2012 4 comments

Last week I was configuring some new vSphere 5.1 (Enterprise) hosts in a dedicated cluster and created some VMFS 5.58 datastores at the Dell Eq. PS6000 SAN with latest firmware, after configuring SIOC I received this error message:

The datastore is connected to one or more pre-4.1 hosts that do not support Storage I/O Control.

That’s weird, I’ve reinstalled all hosts (not updated) and created new datastores, there are no vSphere 4.1 hosts in this cluster (even connected to the datastore) and the PS6000 supports SIOC..

 

Solution:

Not really a solution.. but you can only configure SIOC with the Enterprise Plus license.. crap!

VMware: Unable to load module /usr/lib/vmware/vmkmod/vmfs3: failure

March 29th, 2012 5 comments

Today I was installing VMware vSphere ESXi 4.1 at some brand new BL460 G7’s.. after creating a new array I started the installation, after F11 to “Accept and continue” I received this error message:

vmkctl.hostctlexception: unable to load module /usr/lib/vmware/vmkmod/vmfs3: failure

Solution:

To resolve this issue, download the ESXi 4.1 HP build from HP at https://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=HPVM06.

  • This issue has been observed on these servers: 
    • HP BL 685c G7
    • HP BL 680c G7
    • HP BL 495c G5
    • HP BL 465c G7
    • HP BL 460c G7
    • HP BL 490c G7
  • After I Installed the HP version (always recommended but this customer installed the other hosts with the original installer) the setup completed!


More information from HP:

The Broadcom bnx2x VMware ESX Driver Version 1.54 does not function with HP Virtual Connect Device Control Channel (DCC) and SmartLink features on ProLiant and Integrity server blades configured with the NC532m or the NC532i adapter running firmware version 2.2.6. After installing or upgrading VMware ESX/ESXi 4.1 the following functionality is either not installed or is lost:

  1. New installation – DCC and SmartLink functionality is unavailable in an HP Virtual Connect environment with the NC532m or NC532i Network Adapters after installing VMware ESX/ESXi 4.1.
  2. Upgrade installation – If the bnx2x Asynchronous Driver Update CD version 1.52 was previously installed on a VMware ESX/ESXi 4.0 host, DCC/SmartLink capabilities will be lost after upgrading to VMware ESX/ESXi 4.1, which will overwrite the bnx2x driver version 1.52 with version 1.54 that is included with the base VMware ESX/ESXi 4.1operating system.
  3. Network failover – ProLiant and Integrity server blades hosting VMware ESX/ESXi 4.1 may lose network failover capabilities that use the VMware ESX NIC teaming failover policy (vSwitch setting) "Link Status only."

VMware: List VMFS version and blocksize of all datastores with PowerCLI

June 14th, 2011 1 comment

For a SAN to SAN migration I need to list all our datastores and blocksizes, It couldn’t be easier to do this with a script. LucD has written a great script to list VMFS Name, VMFS Version and VMFS Blocksize

New-VIProperty -Name VMFSVersion -ObjectType Datastore `      -Value {           param($ds)           $ds.ExtensionData.Info.Vmfs.Version      } `      -BasedONextensionProperty ‘Info’ `      -Force

New-VIProperty -Name VMFSBlockSizeMB -ObjectType Datastore `      -Value {           param($ds)           $ds.ExtensionData.Info.Vmfs.BlockSizeMB      } `      -BasedONextensionProperty ‘Info’ `      -Force

Get-Datastore | Select Name,VMFSVersion,VMFSBlockSizeMB

Output:
