I found my ESX servers could not recover the 65th LUNs that I tried to present to it and myself did log a support call and still pending the reply from VMware. Beside that, I found another interesting article with the details below.

In Multipathing Configurations the Number of Paths Per LUN Is Inconsistent
The hpsa driver in ESX Server might reduce the number of supportable LUNs below the expected maximum limit of 256 when the controller is used in multipath configurations. In multipath configurations, if all four paths are configured, the total supportable LUNs is reduced to 64. In certain multipath configurations, because each target path consumes an available LUN slot, the total number of supportable LUNs might be reduced to 60.

Latest industry news show that both Microsoft and Redhat had finally agreed to support each others in their virtualization technology to allow inter operation and support to each others. Beside SuSE Linux, we will later see the Redhat able to be run on Microsoft Hyper V. For consumer, is a good move absolutely for both Microsoft and Redhat users which allow their customer to standardize and consolidate their virtual environment more efficient. But if we compare both to VMware, I will say they are still far behind as we can see the capabilities from VMware to interop with any operating system base on x86 or x64 today.

While I was trying to create a new virtual machine from template, I’m getting an error message: Failed to deploy template: A general system occured: Failed to create journal file provider.
I found the problem because of “/var” partition are running out of space. Damn!
During my previous VMware ESX setup, the partition setup are configure as DEFAULT which is 2G for “/var/log”.
[root@esxserver root]# df -kh
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 4.9G 2.1G 2.6G 45% /
/dev/sda1 99M 28M 67M 30% /boot
/dev/sda6 2.0G 496M 1.4G 27% /var/log
Normally, /var partition won’t be filled up easily(1st time encounter this problem) and for some reasons, total of 36 /var/log/vmkernel* related files are fully occupied the /var partition.
