Newly released Acronis True Image 2019

Try this, I think this may give you the info. I don't have access to ESX 2.5 and can't verify

List the attributes of a VMFS volume or a raw disk mapping
-P --querypartitions <VMFS_volume_name>
-P --querypartitions <VMFS_volume:fileName>
For a VMFS_volume_name, the listed attributes include the VMFS version number
(VMFS1 or VMFS2), the number of physical extents (partitions) comprising the
specified VMFS volume, the volume label (if any), the UUID (if any), and a listing of the
SCSI device names of all the physical extents comprising the VMFS volume.

Hi ,
We have tried vmkfstools command with -P flag but its not giving desired
info. (block size information), any how we have tried  vmkfstools with -l
flag which gives block size but not sure about that.

thanks

what happens when you're in VI Client and you do properties on the volume?  Can you do a screenshot?

Another way to find out is to create a 258GB partition on a VM (if you have room).  If you can't make a partition than you know that the block size is 1MB

This is what I found here: http://communities.vmware.com/message/469530
--------------
If you're using the VI client already then it's listed in the configuration->storage section when you click on the volume.

If you're still using VC1.x and ESX2.x then type vmkfstools -l vmhba0:0:x:1at the service console.

Where x is your LUN number. (not always a 1 either, ls your /vmfs directory)

This will give an output like this:

Name: your volume name (public)
Capacity 1901273439744 (113321 file blocks * 16777216), 687865856 (41 blocks) avail

The 16777216 is the blocksize in bytes, in this case 16MB.

I never knew ESX 2.5 had the ability to create such huge block sizes!!

A normal ls -lh of your VMFS Datastore would provide you this info.
