Hi Team,

I have a question for Dell PowerEdge R710 server. Currently this server has 3 x 146GB HDD and OS was loaded and application are installed and up and running. Now we would like to replace these drives with new 3x 450 HDD. how about going to replace new disks?

quesitons
does this required downtime or can this be done on fly?
can we remove one 146 HD out of the server and insert new 450 HDD, is that works? (since the HD size is more than the size of existing disk

Please suggest how to do this?

thanks in advance

The requirement has been changed now.... we can keep the exiting hdds as it  is and now we need to add 3x450 HDDs to the server. could you tell us how about adding new disks to the server?

again, can this be done without downtime? we have open manage software installed already.

thanks

First of all make sure you have enough empty drive bays available on that server. As far as I can see, that model comes with either 4, 6 and 8 bays. If you have the small 4 bay version you won't be able to do this (you'd need something like a powervault to add the HD's).

2nd, it depends on your RAID controller. Again as far as I know you can get this server with different controllers. So check the manual of yours. The good controllers allow you to just insert the new disks while the server is running, then use the RAID configuration utility to create a new array with your new HD's, and when that is done the new space will be available. Depending on the OS you are running you may have to reboot to get it to recognize the added space.

I believe its Controller PERC H700 Integrated...

You mean to say if its 6 and 8 bays server then we dont have any issue right? How can we figure out if its a 6 or 8 bay? Can we do this through open manage?
Is there any documents or steps to insert new disks and create a new array?

ITs Red Hat 6 OS on this server so would I need to reboot the machine

thanks for your answers

Just look at the front of server, if you can't see the bays right away because of the front cover, just remove that. You should see how many bays there are then. You can probably also get that info via the invoice.

You can get to the manuals via the Dell Website, select Driver downloads, enter the server's ID TAG, and then you can select manuals...

I'm not sure whether RH6 needs a reboot. If the new volume is seen using gparted or fdisk, then a reboot isn't required, you just will need to partition the new volume (I prefer using gparted, but RH6 may have it's own utilities for this).

I've justed simulated adding a virtual disk to a running CentOS6 Virtual Machine on VMplayer, and the disk utility didn't recognize the new HD. So you will probably need to reboot.

I do not have physical access to the box cause I am working remotely

I will look at the manuals for creating an array...if you do have steps or manuals in generic that will help..
thanks

A small question on the same thread...

Here is the config we have on DELL R710 server

PERC H700 Integrated Virtual disk 0
Connector 0 on PERC H700 Integrated

Physical Disk 0:0:0 to  Physical Disk 0:0:2 (total 3 disks of each 136 GB with RAID 5)
capactiy: 136 GB
Hot Spare - no
Serial No.xxxxxxx
Part Number xxxxxxxxx
Negotiated Speed3.00 Gbps
Capable Speed3.00 Gbps
SAS disk

Connector 1 on PERC H700 Integrated
No disks

now that our requirement is, i have brand new  3x450 HDD in which 2x450 can be created a new virtual disk (ex virtual disk 1) with either RAID 0 or RAID 1 (hope RAID 5 cant possible since it requires 3 drives) and 1x450 can be used as global hot spare...
can this be done? if so, should we do this from DELL BIOS utility or from openmanage?

Please note that we have virtual disk 0 already on the box with 136 GB so global hot spare (450 disk) can be compatible with this array in case of disk failure and automatic rebuild happens on 450 GB disk????

Hope I made it clear?

thanks

I wasn't able to get online for a couple of days. Also, as this Question is very old (your previous post was in September) it'll be very unlikely that anyone else will drop in and take a look at it. Apart from that I don't really understand what you are asking in your last Question...

I think it is best to close this one and open a new one with your new Question, but try to formulate it so that we understand what it is you are trying to do ... ;). That way other experts will see the new Question too...
