EventID 9 Error The device, \Ide\IdePort0, did not respond within the timeout period on vmware esxi 5.5 machine

Hello,

I have a VMWare virtual machine, a Windows 2003 server with Microsoft Exchange 2007.
The VMware host is an VMware Esxi 5.5 .

The server is very slow (and even for the Outlook clients).
And since the slowness began, i've noticed this error (the frequency is variable, several tens per day):

 Event ID 9 Source atapi
 Event ID      9
 Source      atapi
 Type      Error
 Description      The device, \Ide\IdePort0, did not respond within the timeout period.

(in reality the message is in french: "Le périphérique \Device\Ide\IdePort0 n'a pas répondu dans le délai imparti. ")

I don't know if the message is the cause or the consequence (may be no Relationship with the error?)
There are other event items (like Exchange events), but they seems to be consequence of the slowness.

Any idea?

Best regards.

Jean-Marc

Okay, well your performance is POOR, because of the snapshot.

The solution

1. Take and create a new snapshot.
2. Wait 1-2 minutes.
3. Select DELETE ALL
4. Wait and Be Patient.

You may want to check the size of snapshot, and also you have storage space free, snapshot deletion, can take, seconds, minutes, hours or days, depending on how long the VM has been writing to a snapshot disk.

don't know how to check, see  my EE Article

Hello Andrew,
Your are right, we have a replication with veeam for this machine.
And it seems there is a snapshot remaining on this machine "TEMPORARY BACKUP VEEAM SNAPSHOT" with a date close from the first event ID 9 (21th of July).
But what can I do?

do you have a snapshot - check ?

also do you have any ide devices in the VM ?

Do you mean if I've verified that the machine is running on a snapshot disk?
In this case, the reply is yes (I'v juste verified)

I'm not sure to use an IDE device. It seems the virtual DVD-CD drive is assigned to an iDE virtual node.

Do you think the solution consists to delete the "TEMPORARY BACKUP VEEAM SNAPSHOT" remaining?
There is no active task for the veeam replication, the ask has beee temporarily been disabled., but the last veeam task has failed, because I've stopped it before a reboot of the server .

Hello,
Thanks, I think your are on the right track.   ;-)
But why not delete the only remaing snapshot, rather than creating a new one and delete all?

because this is a sure way, of making sure the snapshot chain is valid...

and delete ALL then merges the entire chain!

There are many methods to achieve the same results, also sometimes, there are no snapshots listed in snapshot manager when they have been completed through the API.

You was right, Andrew. We have juste delete the remaining snapshot (I know you advise to create a new one before, but we have done that).
We have  good performance again.
I thank you for your help.

no problems, keep a daily check on those snapshots.
