3 Node Oracle 10g RAC
3 HP DL580 G4 + EVA4100 Storage
RedHat Enterprise Linux 5

We have an ORacle10g RAC having 3 nodes and this problem is occuring on first node.

The error comes at the first screen as follows:

scsi 0:0:1:0 unexpected response from LUN 1 while scaning, scan aborted
scsi 1:0:0:0 unexpected response from LUN 1 while scaning, scan aborted
scsi 0:0:2:0 unexpected response from LUN 1 while scaning, scan aborted

System hangs at the folling during bootup

If we comment lines for Luns within the /etc/fstab, system boots up to the command prompt but we are not able to mount the ocfs2 filesystem on the SAN.



Following drivers and software used for HBAs to configure and manage SAN connection.
1. hp_qla2x00src-8.01.03p4-20b.linux.rpm
2. qlafc-linux-8.01.07.15-2-install
3. fibreutils-2.3-7.linux.x86_64.rpm
4. standalone_sansurfer5.0.0b17_linux_install.bin

1. assuming that's a legal copy of RHEL, I'd phone them (or Oracle, depending on your ctc). You're paying for support and it'll be quicker than Q & A here for something like that.
2. you may want to ask the mods here to move this to the RedHat forum for better exposure. Use the 'Report' button at the bottom of you post.
