Adding More Storage to a Dell PowerEdge 2900

Our PowerEdge 2900 is running low on disk space. We have 8 drive bays on this server and 4 of them have drives in them configured as RAID-5. I've added disks to other Dell PowerEdge's in the past using the Dell OpenManage Server Administrator and it's usually straightforward except this time I notice this server seems to have two "connectors".

In the OM Server Admin software if I drill down to System > Storage > PERC 5/i Integrated, I have one Virtual Disk 0 set up in RAID 5. I also have "Connector 0" and "Connector 1" ... I think these are separate backplanes. I see the original 4 drives on Connector 1 and the new 5th drive showing up in Connector 2.

My question is - Can I use this extra drive on Connector 2 to extend the RAID partition without destroying the data like I've been able to do on other PowerEdge servers? If not, can I at least add this drive as additional storage - even if it's not part of the array?

you should be able to add the disk to the existing virtual disk and expand the array and volume as you did on previous servers

The only options available for the Physical Disk are "Blink", "Unblink", "Assign Global Hot Spare" and "Clear..."

The options on the Virtual Disk are "Reconfigure", "Delete", "Check Consistency", "Assign/Unassign Dedicated Hot Spare", "Blink", "Unblink", "Rename", "Change Policy", "Slow Initialize", "Fast Initialize".

Which one of those options should I be going to in order to add the drive to the array? I don't think I did it this way on my other servers - this seems unfamiliar having the second connector in there.

You can do either...the perc/5i will let you expand your raid 5 set with the reconstruction wizard.  There should be no problem using disks from either channel...you can also use the disk individually, as a new logical volume.  Make sure you backup before adding the disk to the array.

Perform this task from the OS using Dell SAS RAID Storage Manage...select virtual disk > Oerations > Advanced Operations > Reconstruction Wizard
Reconfigure is the option you want to use in openmange, and when going through the wizard make sure you increase the array size as sometimes it defaults to the current size and doesn't incluse the new space unless you choose to increase it, not sure why it does this but it seems to be a common issue lately. As mentioned above make sure to take a good backup before hand and while tht reconstruct is running try to keep the traffic on the server light and do not restart or shut the system down while it's running. Once its done the added space will show up in disk management as unallocated space.
