Programming Raid Controller

DTA01 — Sun, 04 Sep 2011 19:52:45 +0000

I know there is software raid and hardware raid. Do you program them the same way? As well do the controller’s have to match drives such as SATA or SCSI? Please forgive this basic question I am new at this stuff.

How do I force a Sun x4200 with a LSI SAS1064 RAID controller to resync?

How do I force a Sun x4200 with a LSI SAS1064 RAID controller to resync? mpt-status returns OUT_OF_SYNC for one of the drives. A power cycle didn’t alleviate the problem. Does this mean the disk has failed?

Rebuild my RAID controller?

WindowsServerATE — Tue, 09 Mar 2010 14:42:05 +0000

If my RAID controller is down and being replaced, would it still be able to recognize the RAID array? Or do I have no alternative but to rebuild everything from scratch?

Dell PowerEdge 2800, 5 physical Maxtor’s, 1 RAID 5. RAID controller or hdd failure?

Ilythiiri — Mon, 21 Sep 2009 15:05:29 +0000

An above mentioned server was taken out of storage after 3 years. (storage was proper – sealed packaging&moisture absorbers)

[strong][/strong]Does not start: 2 of 5 raid disks show “failed”, both in RAID BIOS and LED’s on the front panel.

I tried swapping 2 failed drives with 2 good ones in other slots. I got
all 5 occupied slots show green “ok” LED’s. But, BIOS utility still
show same 2 slots as “failed”.

So:

can it be RAID controller’s fault? / i got 2 drives gone dead on shelf in airtight package? / i am missing something simple? / something else?

Migrating two new 1TB drives to RAID 5 array

Atumisk — Wed, 19 Aug 2009 03:03:51 +0000

Using AMD’s RAIDXpert, I added two new 1TB drives to an existing RAID 5 array. The existing array already held data. After migrating the new drives (assuming this would allow me to save my preexisting data) and restarting my computer, I am asked to reformat the array. I would really like to recover the data. Is there any way I can do this?

From 3 disk RAID 5 to 5 Disk RAID 5. All 1TB.

Can RAID 0 volume be deleted and re-added with no data loss?

Rsheldon62 — Wed, 07 Jan 2009 15:44:34 +0000

I have a Dell Precision 690 Workstation
with an LSI Integrated RAID controller.

I have a 2-disk RAID 0 (what LSI refers to as an
IS or Integrated Striping) volume.

Recently the motherboard was replaced (and the RAID
controller is integrated onto the motherboard).

Ever since the motherboard replacement, I get the
following error at boot time:

Dell SAS 5 Host Bus Adapter BIOS
MPTBIOS-6.12.02.00 (2006.12.22)
Copyright 2000-2006 LSI Logic Corp.

Integrated RAID exception detected:
Volume (00:130) is currently in state INACTIVE/OPTIMAL
Enter the SAS Configuration Utility to Investigate!

I can temporarily resolve this problem by activating
the volume in the RAID configuration utility:

select SAS1068
RAID properties
Manage Virtual Disk
Activate Array
Y

But if the power is disconnected, then the same error recurs
on the next boot.

I am thinking that if I delete the volume and re-add it, then
the problem will go away, but I’m afraid I might lose all my
data if I do that. Does anyone know if that’s true?

Any help appreciated.

Thanks,

Roger

Upgrading Computer Motherboard that currently has two RAID 0 setups

Mgbtp — Wed, 16 Apr 2008 18:01:47 +0000

I will be upgrading my computer components with a new motherboard and currently have a RAID-0 setup with my old mb’s built-in Promise FastTrak 378 controller. I also have a Promise FastTrak TX4310 pci card controller with another RAID-0 setup. Both have two drives each.

Will I lose data on either setup moving to the new mb’s built-in RAID controller? I would like to not transfer my pci card controller if possible (without losing data on these drives).

Thanks,
Mike

Installing RAID 1 on XP machines or use server software?

Jtennyson — Fri, 13 May 2005 09:32:06 +0000

We have a mission critical robot on the production line that is run by 3 pc quality machines running NT4 workstation. They are referred to as A B and C It has crashed 2 times in the last year. Both times it was the motherboard on PC B. This machine runs 24×7. The IT department has not had much input into this machine until now.
This is what we would like to do.

Replace all three motherboards (They are currenly Pentium 2). The industrial motherboards only come in pentium 3.
Replace the operating system with a current one.
Mirror the harddrives for disaster recovery.

My question is: Because these machines do run 24×7, would it be better to use Windows 2003 and mirror the drives through the software. (Will 2003 standard run on pentium 3?) Or would it be OK to use XP and use a RAID controller. And if I do use a hardware solution, what is a good controller and harddrives to buy.
