problem with raid configuration

Hi all,

I installed a brand new DL360 G4 with 2 ULTRA320 SCSI disks, each 36 GB. I configured it using a single logical drive split in two partitions (raid 1).
Using the diag tools, this is the output (see below), which looks fine to me.
However, when I shutdown the system and remove one disk, the system complains no OS was found, If I remove it when the system is online, it crashes (windows hard error)...

Anyone knows what is wrong ?
Thanks in advance !

Re: problem with raid configuration

Marco:


The first thing I would do, based on this output, is update HDD firmware so that they match. Though not likely the problem, it could cause issues.

Second, check your array. Make sure you actuall have the 2 drives defined in the array. Within Windows, run the Array Configuration Utility to check things out. Alternatively, you can reboot and enter the bios setup utility for the SA Controller when prompted (just after initialization, hit F8).

Other than that, and not having any more information, I am not sure if I can provide any more suggestions.

Re: problem with raid configuration

Just noticed you had two different drive models as well. Might be that combination with different firmware, even though I still feel that it's unlikely.

Re: problem with raid configuration

Hi Marco,

The firmware of the HDDs & SA6i has very little to do with the issues you are facing.

Possibly, this is what happened in the two scenarios:-

1. When you shutdown & remove either one of the HDD, you must acknowledged the new status when prompted by the RBSU upon next POST. You must either press F1 or F2 to acknowledge it, otherwise, it will chose F1 by default(which will disable any logical drives it found). To continue to boot up from OS, you should select F2 to fail the physical drive that is not responding (is this case - "removed already"). The OS should boot up nicely with single HDD.

2. The only reason why the OS crashed when you tried to remove either HDD is because; whenever you re-hotplugged the HDD back to the original slot, the rebuilding process takes place immediately. During rebuild process, any removal of HDD should be prevented till process completed. In your case, you could have pull out the HDD while the rebuilding is still in progress.

You can use ACU to check the status of your logical drive. If status is OK, then you could safely remove either one HDD while OS is running.

Hope this helps.


Cheers!!

Re: problem with raid configuration

I concur with AK. This firmware talk has nothing to do with it and is not needed. AK has id'ed the most probably cause, that the unit is rebuilding.
I would also suggest that the configuration has changed some how and each drive is now configured seperately and the original RAID1 is broken, therefore the removeal of the drive could cause a crash since there is no longer redundancy
