Thank you Edward.
However even following the readme.txt section 3.1.3 for SLES11 on RAID, XEN install did not help.
I still receive ' Could not find /dev/disk/by-label/mainos'
I've tried to use by-id, by-label, by-uuid, by-path for a XEN boot but no joy.
The system boots to non-XEN just fine, which uses by-label. Use to have by-id before reinstall which worked for non-XEN.
Any more suggestions?
PS: how can I tell what system board? S2600CP, S2600CP2 or a S2600CP4? I need to ensure it is a S2600CP4. Sticker under the stencil of S2600CP states 'PBA E99552-507' and 'QSCP22001800'.
OK here is how I understand...
There are two drive diskette images in the driver package you need to load during installation:
1. megasr-15.00.0927.2012-1-sles11-sp2-x86_64.img. This is the normal SLES driver. Name of the driver is lsi-megasr-kmp-15.00.0927.2012-1_3.0.13-0.27.x86_64, which seems working properly.
2. megasr-15.00.0927.2012-1-sles11-ext-sp2-x86_64.img. This is the XEN driver. Name of the driver is lsi-megasr-kmp-xen-15.00.0927.2012-1_3.0.13-0.27.x86_64. Could you confirm if this one is also properly installed? .
I installed the lsi-megasr-kmp-xen-15.00.0927.2012-1_3.0.13-0.27.x86_64 so both are listed in the non-XEN boot.
Now when I boot into XEN, the system take a loooong time to boot, over 30minites and still no logon screen. During the boot, this is displayed over and over again.
Uhhuh. NMI received for unknown reason 00 on CPU 0.
Do you have a strange power saving mode enabled?
Dazed and confused, but trying to continue
The BIOS 'Power and Performance' is set to Performance.
I was using the Enhanced Rapid Storage Technology II in the BIOS settings, the ERST2 hardware configurations and the lsi-megasr -kmp-xen SLES 11 SP2 driver to make this all work, which did not work. Looks like Intell needs to check the drivers for the ERST2 under linux.
I have now switched over to the regular Rapid Storage Technology in the BIOS settings, the RST hardware configuration and the iastor (ide) SLES 11 SP2 drivers. Now the system boots up fine in non-XEN (and faster) and XEN mode.
