Hot Swappable SATA Drives

I have a ML 350 G5 server. We have hot swappable SATA drives. There are two that are in use in a RAID 1 configuration. We want to use the third for disk to disk backups. My problem/question is when we attempt to unplug the drive from the hot swap backplane, Windows 2003 gives write delay errors. Plugging the drive (or another) does not correct the issue. When the machine is rebooted the user has to accept (pressing F2) that the drive was indeed removed.

Is there a way to unplug the drive without these errors occurring (such as Safely Remove Hardware option)?

The controller is an Smart Array E200i embedded controller.

Any feedback would be great.

Re: Hot Swappable SATA Drives

The third drive is configured as a separate array (RAID 0). All lights on the caddies are the same (green and blue). The screen shot for the ACU are included. When I click on view status alerts I get the message that there are no status messages at this time (I can indlude that one if you want)

Re: Hot Swappable SATA Drives

in acu click on the disk that is alone the light should go blue on the disk

ensure you pull the
disk that lights up..
not one of the other two in the raid set.


if it still plays up and 3 disks out

and on boot go into controller and erase the arary F8 reboot
then add the two disks in the raid set back to their slots and all should be ok..

and then you have the spare disk in you hand,,

Re: Hot Swappable SATA Drives

I am a little unclear. You want to pull out the drive that is not in the RAID 1 set, then delete the RAID 0 drive so that it is in hand?

Re: Hot Swappable SATA Drives

no

go in acu click on the drive the one that is alone the one you want out

it should light blue pull that out if all is okay fine.

do not pull a disk that is part of the array

if this works then all is fine

try it then let us know

Re: Hot Swappable SATA Drives

now if it still plays up do this

if you have a tape backup


pull all 3 disks out

and on boot go into controller and erase the array info by pressing F8 reboot

then add the two disks in the raid set back to their slots and all should be ok..

and then you have the spare disk in you hand,,

Re: Hot Swappable SATA Drives

I pulled out the spare drive when it was blue. After a few minutes, the Windows write delay message appears. I opened the ACU and see the messages that the drive is bad or missing (which is what I would expect). I am attacing a screen shot so you can see the messages.

I do not have a tape drive. So I am a little weary of pulling the drives out and deleting the array.

Re: Hot Swappable SATA Drives

I powered the server down, pulled all three drives out. Rebooted. When the system comes up to the array in the boot sequence but it does not give the option of pressing F8 to enter the utility because it detects no drives in the system

Re: Hot Swappable SATA Drives

if you have no tape back up make one and proceed as i described,,


when done in acu you can delete the array you do not want the single disk

then pull it out

Re: Hot Swappable SATA Drives

I do not have a tape drive. And when I pull out all of the drives, I am not allowed to enter the array controller configuration because it detects that there are no drives.

Re: Hot Swappable SATA Drives

When I physically take out the disks, I am not given the option of pressing f8 to enter the array utility. I will check to see if the firmware of the controller is older but I am still having the same issue.

Re: Hot Swappable SATA Drives

I have discovered the problem that I was having. I will post here in case someone else is trying to accomplish the same task but encounters the problems that I did.

I could not use the same controller that contained the OS raided drives. I added a second controller and a hot swappable caddy to the system and all works as expected.

Thanks for trying to assist.
