Note 516.0            SWXCR and invalid OS selection..help            No replies

--------------------------------------------------------------------------------
    I have a 4100 with two SWXCR'S and one KZPBA. I installed NT 4.0 on
    disk 0 of SWXCR 0. No problem, boots fine. Now for the detail, and
    the problem. (AlphaBIOS 5.24)
    
    SWXCR 0
    		All 7 drives are configured as JBOD.
    		NT 4.0 is installed, boots and runs fine on disk 0.
    		WINNT partition is NTFS, system partition obviously is FAT.
    
    Everything is working perfectly.
    
    I then want to create one logical RAID drive from 5 of the disks on
    SWXCR 0. I start SWXCRMGR and create a group and logical drive using
    the last 5 drives on the controller (not touching drive 0 which as NT
    4.0). No problem, until i try to reboot.
    
    Now I get the "OS Selection is invalid"...it can't find the osloader
    files on disk 0 partition 2, as is specified. This has not changed.
    Hard disk utilities shows disk 0 as having the NTFS and FAT partitions.
    
    Does making any RAID changes on the SWXCR the OS is on cause it to
    be damaged, ie not bootable? What has happened, and how can I recover?
    
    thanks....... Steve

5763.1no ideas, pointers, or clues?LEDER1::BENDELWed Mar 05 1997 06:107
    nobody has any ideas on how I can recover from this? Seems reinstalling
    NT is not the best way, but could be done.
    
    If there is a better forum for this (storage???) I'd appreciate a
    suggestion around that too.
    
    help guys....:)   Steve

    Steve,
    
    It appears no one has any ideas, so I hope you are pursuing answers
    via official channels.
    
    Good luck,

	I'm taking a shot in the dark on this one... When I have used
	SWXCR for RAID (haven't used them for JBOD), one of the unit
	numbers, scsi(?) or rdisk(?) or something (I forget), is listed
	as 8, not as 0 as I would have expected.  So even though you
	didn't change anything from a hardware standpoint, maybe changing
	from JBOD to RAID did cause something to happen.  Go into your
	hardware setup and make sure that the numbers are what they
	should be.

	Oh yeah, the 8 is correct.  Don't change it back to zero.  That
	might not have been clear from my previous response.

5763.5Hardware Problem?QCAV01::VARUNMon Apr 21 1997 07:4714
    Hi,
    I was just reading this,and I remembered this benchmark we conducted 
    for an Alpha Server 4100,with a KZPSC(4MB Cache),and 6*2GB,RAID5 with 
    1+5 HDD;with the one extra disk on the BA356 used as the OS disk.
    
    We had a problem in rebooting,but this was a Hardware Problem...
    we had a KZPSA controller card in the machine along with the KZPSC
    card. We were able to boot normally,once the KZPSA was removed,and then
    the KZPSC installed. Post installation of the KZPSC,the KZPSA could
    be added.  I am not sure if this is helpful,as I'm not sure of the
    KZPBA...just thought,this might be helpful?
    regards,
    
    Varun
5763.6.0 should have said KZPDA (not KZPSA)LEDER1::BENDELTue Apr 22 1997 08:584
    in the base note...KZPBA should have been KZPDA...sorry  :)
    
    and thanks.for adding to the string..you can never have too much info
    about peoples experiences with controllers....
5763.7compare os selection setup with disk...KOKY::PEREZWed Apr 23 1997 09:308
    Since this is a 4100, when alphabios comes up go to HARD DIKS SETUP and
    look at the disk number that the SWXCR disk 8 has (i.e. DISK 1, 2, etc)
    The go to the Utilities Menu, OS selection Setup and see if the disk
    number matches the want the that the boot partition is located at. You
    can, while in the OS Selection Setup us F9 to validate your boot
    partition. If it doesn't change it and validate again. Remember that if
    you ADD disk controllers this may change your boot partition number
    depending on which slot the new disk controller was installed.
