Hi,
I n our ESX 3.5i server, if i issue df, I get below list of filesystems (I havent taken SAN filesys to considerations)
Filesystem Size Used Available Use% Mounted on

I'm little confused with the filesys architecture of ESX 3.5i and want to know, what are all these filesys? I have given the contents of each filesys
Yesterday, when we had problem with the server, we were not able to see the 3 filesystems. (out of above 6). After reboot we found all filesys.

This will give you a bit of background on some of the partitions - http://www.vm-help.com/esx/esx3i/check_system_partitions.php. The root partition (190 MB) in a RAM drive and the other partititions are mounted below it. Your large one will be your VMFS datastore and the others are bootbank / altbootbank / store and scratch.
In your case

thanks a lot
Under any circumstaces, is there any chance for filesystem missing?
Though all the filesys are in the same hard drive, yesterday 3 FAT filesys were missing. Reboot has fixed the issue.
/var/log/messages had SCSI TIME OUT errors like below..

Under normal circumstances it should not disconnect. Might be worth running a hardware check on the server.
