Hello ,
We performed successful backup recovery and log recovery and the system was up.
But once we stopped system and try starting SAP again .
It gave error while DB start. Saying Disk not accessible .While checking for logs in krnldiag file .
I found this error .

We already Rebooted the server . But that doesn't work .
The file system SAPDATA1 is a NFS mount on the system from SAN .
I checked via lsof but din't got any clue . One thing which i think have to do with this may be the hostname.
We used a virtual hostname for installation . But the physical hostname is different and both of them are pointing to same IP .
so first time we started SAP was with command startsap HOSTNAME .
Also there are no multiple instances on the system . there is only single instance.
So please suggest any further steps so as to analyze the problem .
Thanks & Regards,
Garima
