PROC-26: Error while accessing the physical storage Operating System error

Hello; Sorry for delay response. Oracle 10g RAC Installation already done in Windows 2003 but not able to post.

Oracle Version: 10.2.0.1 

Os : Windows 2003 SP2

Shared Storage: RAW 

Using the above configuration I was done RAC Installation but during installation  i was facing some issues; I would share you my installation & troubleshot experience.

The below error & warning message got from Installation inventory logs and CRS,CSSD from both nodes. According to oracle document there is some firewall issues as well as need to disable UAC (User Account Control)

From my case I don't have UAC & firewall also disabled but still not able to install RAC on Windows 2003.

When I try to analyze the problem have found two things. 

1. OCR & VOT Disk not able to access from both nodes. 

2. Oracle 10.2.0.1; This is BUG we would have to install 10.2.0.4 Patch in RAC. 

How to resolve  this issue:

1. Configure your shared storage as per document & install 10.2.0.1 Cluster on both nodes.

2. When you complete installation you may face some error for post installation. ( Just ignore it )

3. Disable CRS on both nodes.

4. Change startup type to manual for oracle related services. ( Using Regedit - Try to change startup type other wise you may face other side effects ) 

[ Regedit -> HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Services -> OracleCSService -> Select (Start) -> Edit -> Specify 3 in Value Date ]  Repeat same step to for all oracle related services. 

5. Reboot your both nodes & install 10.2.0.4 continue post installation activity. Please let me know if you have any trouble and question :-) 

Thanks ..
