- Thanks for these postings. My problem, however, is not the SCSI address.
- I have tried two different addresses. And actually, the disk appears to work
- fine up until I allocate it's space to filesystems. With the disk in the
- system and configured as part of rootvg, I can reboot many times without
- incident. The symptom of the flashing 223-9 sequence only occurs after I
- allocate the space and then reboot.
-
- Some have suggested it is an AIX bug involving large external disk drives
- greater than 1GB. Can someone confirm this? Would it be a bug that would
- be fixed by AIX 3.2.3? We are running AIX 3.2.0.
-
- Another person suggested I need to reset the NVRAM by removing the battery.
- Is there a way to reset the NVRAM without removing the battery?
-
- Thanks in advance.
