Same Hosts or different Hosts?

Take a look to /var/log/vmkernel.log

Hi Joerg,

Thanks for your response..

Just Consider the case of one host.

Also what could be the possible reasons for it ?

any syntax/particular parameter/keywords which we can check in VMkernel and hostd logs ?

what could be the possible resolutions for such issue ?

The title of your thread is somewhat confusing. You say "showing offline and online". These are two competing states, so what exactly are we seeing here? Feel free to post screenshots demonstrating what you see in your own environment.

4 If a VM snapshot 2 is corrupted out of 4 snapshots, can I use snapshot 3. If yes then how? if no then why ?

5. If vmkernal port is not working what could be the issue ?

6. What is difference between Stripping and Strayiping (in RAID configuration)
