Level 6

Hi All,

 

We are experiencing another 156 error (they are a pain) on a Windows client backup.

When I logged into the client to check that this list writers stable for some reason I recieved the error below.

C:\>vssadmin list writers
 

'vssadmin' is not recognized as an internal or external command,
operable program or batch file.

 

I have attached logs  *bfis and bpcd" I have viewed them and can't find anything specific. If someone can take a look and see if they can let me know.

 

Here is some info

Client Server Windows 2003 SP2

Netbackup client 7.6.0.1

 

Thanks

Hi,

 

You'll need to resolve this issue as the VSS writers seems fine. If its constantly happening you can check if there is enough free space on the C drive. Basically you'll need to check with OS support.

The shadow copies of volume C: were aborted because of an IO failure on volume C:.

I think you should focus your attention on "'vssadmin' is not recognized as an internal or external command,
operable program or batch file."

 

Any vss errors in event viewer?

Hi Riaan,

Thanks for your response, yes the "vssadmin" command not being recongize is odd.

 I found the following error in the event viewer.

I believe volsnap is from netapp? You using netapp in the env? If so try http://www.symantec.com/docs/TECH156732

Riaan,

This is a Client's server I am not sure if they are using Netapp or not. Is there a way to check the server to see if its using Netapp?

should I disregard the symantec tec doc? The backup will get the same error tonight as is.

 

Thanks

volsnap in this case is probably the part of the windows volume manager which vss calls

A busy volume can give this volsnap IO error, a solution can be to increase the mindiffarea so that the shadow area does not have to grow while the backup is running. Does chkdsk show any errors on this C: drive ?

Have the post below helpful when troubleshooting status 156 on windows

The standard questions: Have you checked: 1) What has changed. 2) The manual 3) If there are any tech notes or VOX posts regarding the issue

I believe that TECH156732 is applicable here. 
Please follow steps as per the TN.

PS: 
C:\windows\system32 should always be in System and User PATH environment variables.

its a volsnap error in event viewer on server. check its event id share it with us and search on google it could be related to OS. sometimes there is a chance to deregister and reregister VSS dll's .

please check VSS status on client server. on cmd write

vssadmin list providers 

vssadmin list writers

----------------------------

check 2 services microsoft software shadow copy and volume shadow copy both should be in manual state.

go to my computer right click on C:\ then on configure shadow copy. then check size.

-------------------------------

go to host properties -- master server then client attributes, check what options are selected for client server.

if client server name not added, plz add it.

------------------------------

once all these basic options checked n verified. go to run and take windows server backup(it is native window server backup same as ntbackup windows 2003) of shadow copy components.

--------------------------

At last share latest bpbkar,bpfis  log files
