Updating SAP-Kernel

[Former Member]

Hello!

We are trying to find out why our cluster has a fail over every couple of days on a ressource. So we updated the kernel last week, but the problem is still there. We also learned today that there is more than one kernel folder on the windows server machine:

1) i:\usr\sap\prd\sys\exe\uc\ntamd64 (the one we updated)

2) c:\windows\sapcluster (here are some exe files, all outdated)

3) c:\usr\sap\prd\d01\exe (seems to be a copy of 1)

How important is 2)?

Hi,

2) is very important. These are the SAP executables that you absolutely need even if the shared disk bay is not available.

During a fail over for example.

So this could indeed lead to problems with the cluster? Every couple of days the ressource for drive i: gives the error "connection to drive i: lost"... this happens since we updated the kernel in June 2009. Our SAP partner told us about this windows/sapcluster folder...

Hi,

When updating the kernel it is important to update also the sapcluster folder but I don't think this is an explanation for the lost I: drive. You should ask your SAN team to investigate on the subject.

All folders are updated... we have to wait now, if the ressource fails over again the next days... thanks for your help!
