Online Initialization Problems on RAID Machine

I have an NCR 3525 with RAID level 5. NCR(AT&T) Unix sys Vr4 version 2.03.01 I'm trying to install ONLINE version 5.03.UC1. The box says that this online is for use on NCR UNIX version 2.03 The problem is that when I try to initialize I get the following errors. ON THE SCREEN I get the following: tbinit: fatal error in shared memory initialization IN THE ONLINE.LOG I get the following: 17:52:42 I/O error 'read': expect 2048 actual -1 addr 0x0 errno 6 retrys 0 17:52:42 I/O error 'read': expect 2048 actual -1 addr 0x0 errno 6 retrys 1 17:52:42 I/O error, Primary Chunk '/dev/rdsk/c21t5d1s1' -- Offline 17:52:42 I/O read() chunk 1, pagenum 0, pagecnt 1 --> errno = 6 17:52:42 INFORMIX-OnLine Must ABORT Root chunk down. 17:52:42 -- Online Aborting -- us=400024bc, pid=2241, uid=108 17:52:42 INFORMIX-OnLine Stopped Initially INFORMIX said that this version would only run on 2.03. But then they certified that it should run on 2.03.01 as well. INFORMIX says it has something to do with RAID and NCR had to set up the drives different. But of course NCR says that it should work fine. Does Anyone have any suggestions on how to fix this? PS: informix is the owner and group for /dev/rdsk/c21t5d1s1 and the permissions are set 660 Thanks for any help. Robbie Long rlong@sol.cms.uncwil.edu
