All drives in array say, "online" but the array state says "degraded."  Why is this?

Server is rebuilding the RAID.. if you see it is just build 30%..
ones it gets 100% everything should be fine...

Probably because on line 9 and 10 your controller firmware is below the minimum level

Ones rebuild will complete.. everything will be back to normal..
Rebuild Rate                                  : 30%
BGI Rate                                      : 30%
Check Consistency Rate                        : 30%
Reconstruct Rate                              : 30%

Depending on just how much data is on the RAID, if it is still rebuilding by the end of the day, I would call Dell. They will support their stuff over the phone for free. It could just be the firmware as charles said or maybe a bad drive and the RAID isn't fully detecting it. Either way, I wouldn't recommend a firmware upgrade mid-rebuild unless Dell says it's ok.

Anuroopsundd is incorrect here

Rebuild Rate                                  : 30%
BGI Rate                                      : 30%
Check Consistency Rate                        : 30%
Reconstruct Rate                              : 30%

This is the rate at which Rebuilding (if it was doing a rebuild) would occur, not that it IS rebuilding

The information posted does not show the status of all drives or the Virtual Disks, but as tishopper states all drives show online

charlestasse:  Thanks.  You think I can install the new firmware using the below command and then rebooting?

$ update_firmware --yes

Rebuild rate is the disk throttle in a rebuild situation.
It is degraded, because your firmware level is below your management application level.
Usually you should upgrade your BIOS, RAID Driver, RAID Firmware as a minimum.
In this order.
In linux Raid driver means kernel module.

What kind of server is this ?

I suggest to use Dell Server Update Utility DVD (SUU), it will upgrade all firmwares to the latest stable release. You can find it on dells support website.

Sorry for the long delay. Two questions:

1. You think the new firmware can be installed using the command line "update_firmware --yes" and then rebooting? (See )

2. The odds that the firmware screws up and we lose everything on the array after rebooting are:______________.

I would grab the .BIN file off Dell's site then run the following (example file used).

chmod +x PE2950_BIOS_LX_2.5.0.BIN

As far as failure I actually recently upgraded a PERC firmware on a Windows and lost RAID array configuration. So it is possible but I would say rare, what we ended up doing was recreating the RAID array (without initializing) as it was before and everything worked.

Before you upgrade I would suggest a full image based backup of the server. You should also take a screenshot of the array configuration out of OpenManage in the event you need to reconfigure and try to save data.

Over the past 7+ years that the first time I have seen that happen that I can remember.

We haven't installed the new firmware yet because we're scared it's going to take it down so I haven't tested any of these solutions but someday we're going to have to bite the bullet.
