The SBP-2 bridge chip in this disk enclosure is not able to support concurrent access from more than one initiator (host).  You need a disk enclosure with OxSemi chip.  I just updated "[[FAQ#Is it possible to use a 1394 disk drive from two hosts simultaneously?]]" to list this requirement explicitly.

Revision as of 08:43, 19 October 2008

I have bought a Maxtor onetouch 4 plus firewire 400 (500GB) external hard drive to be used as shared drive for Oracle ARC testing. I am following the document http://www.idevelopment.info/data/Oracle/DBA_tips/Oracle10gRAC/CLUSTER_10.shtml I could not get one of the drives listed in the document so I have bought maxtor one touch 4 plus firewire drive. When I tried following the instructions in the above RAC document I could not see the external hard drive. It showed probing the new drive at the time boot and I have selected configure. I have tried the troubleshooting notes shown in the above document also but that did not help. Here are some of the commands I have tried:

I am using 2 dell dimension 3000 systems with Intel Pentium IV 3.0Ghz processor, 80GB HDD, 1GB RAM. Appreciate any help to resolve this issu. Regards kv1394

disk enclosure not suitable

The SBP-2 bridge chip in this disk enclosure is not able to support concurrent access from more than one initiator (host). You need a disk enclosure with OxSemi chip. I just updated "FAQ#Is it possible to use a 1394 disk drive from two hosts simultaneously?" to list this requirement explicitly.
