Re: Moving Oracle RAC VMs from Linux to Windows

Hi,

Managed to find the missing link. We need to rewrite the ASM devices permission rules with the new SCSI IDs.

After attaching the ASM disks in Virtual Media Manager or by manual commands, we need to do the following.

1. Boot Linux image on Virtual Node 1.
2. Find the new SCSI ID of the devices using the command (for OLE 6.3),

/sbin/scsi_id -g -u -d /dev/sdb
/sbin/scsi_id -g -u -d /dev/sdc
/sbin/scsi_id -g -u -d /dev/sdd
/sbin/scsi_id -g -u -d /dev/sde

3) Change the entries in /etc/udev/rules.d/99-oracle-asmdevices.rules to match the new SCSI IDs.

4) Run partition probes and reload UDEV rules.

Voila! +ASM1 instance and RAC1 instance boot up perfectly fine.

5) Repeat the same procedure on Virtual Node 2.

Virtual Node 2 has discovered the ASM disks which is great. But OCSSD daemon starts and dies due to some network error as per the log file. But that is another issue. The main problem is solved which was porting from Linux Host to a Windows Host.

Thanks to everyone, especially Tim's wonderfully informative guide(s) on his website.

Regards,
Anand
