Make sure you SSH into the host that the VM is running.

I miss the “old” esxcfg-mpath

I know many of you may have the same feeling. It was
difficult for me to find the device for a new LUN allocated, as it
had some partition and I had to remove it before I can format as
VMFS. I found some KB articles, but not as easy as the good old
esxcfg-mpath. I will post some detail here later. 1. SSH and type
the esxcfg-mpath command as below to find the naa, where 90 is the
LUN#

[root@abcd]# esxcfg-mpath -b | grep 90
-B 5

naa.60060e80056e350000006e35
: HITACHI Fibre Channel Disk
(naa.60060e80056e350000006e35)

vmhba2:C0:T0:L90 LUN:90 state:active fc Adapter: WWNN:
20:00:00:00:c9:89:56:da WWPN: 10:00:00:00:c9:89:56:da Target: WWNN:
50:06:0e:80:05:6e:35:1b WWPN:
50:06:0e:80:05:6e:35:1b

2. Once you
have the naa, use the following command to find the console
device.

[root@abcd]# esxcfg-scsidevs -l | grep
naa.60060e80056e350000006e -A

3. run
fdisk against the device and create the
partition.

[root@abcd]# fdisk
/dev/sdcf

Select option o to create a DOS partition and then w
to write the changes. And you are set.

4. Go to VC and define the VMFS volume

Unable to start 64 bit VM in VMware workstation?

Wondering why you can’t start a 64bit VM in VMware workstation even after you have enavled VT in BIOS? Make sure you edit the VM and set the CPU Virtualization Engine as noted below.

Error message :(

Why do we still see the door open errors?

Performance Best Practices for VMware vSphere 4.1

The 1st chapter says to test memory for 72 hours. Which tools do you use to test it? I had a host that ran MEMTEST86 successfully for many many hours with no errors, but still had to replace all the memory due to some strange issues.
