Old DL380 Raid Notes

Problem: Where are my disks???

When we installed the os on our new (to us) prolient DL380, Only a single disk was visible in spite of there having been 6 disks installed. This is because the DL380s disk controller was set up in raid mode an did not expose disks until they were configured as "logical" disks.

This is unlike the Dell PowerEdge we have which detects and presents the drives in a hot swappable fashion while still allowing some disks to participate in raid arrays.

Since we use hardware raid mirroring on the boot disks, Adding, removing or replacing disks requires configuring the raid controller.

Configuring the disks using the raid controller bios

... use some words here ...

After several seconds you will see a text based bios screen [[Image(CaptiveRaidController:ILo3SSHConsoleBooting.png)]] After the network controller is started the raid controller will give you a chance to configure it. _PRESS F8 NOW!! _ \ [[Image(CaptiveRaidController:PressF8NOW.png)]]

If you miss it you will have to escape back to the ILO3 and power cycle the machine. (This is ok because the disks are not active until the machine actually boots)

Once in the raid controller bios you will get a main menu.

[[Image(CaptiveRaidController:ViewLogicalDrive.png)]]

If you select view logical drives will see that the first two disks are combined into a mirrored pair and that there are no other drives defined.

So we select "Create Logical Drive". Which gives us the following screen.

[[Image(CaptiveRaidController:CreateLogicalDriveDefaults.png)]]

Notice that the defaults are to create a raid 1+0 array with the first two matching disks. Deselecting either disk (down arrow, spacebar) will cause the raid configuration to automatically drop to RAID 0

Press Enter when finished. The next screen will ask you to verify the creation

Repeat this for each remaining disk.

When you are finished you can view the logical drives. [[Image(CaptiveRaidController:RaidConfFinished.png)]]

The key will walk you back out so you can continue to boot.

Using HP utilities to configure the controller without downing the server

HP provides utilities and officially supports bionic and hosts a repo for it. It includes a server that can be accessed graphically as well as a command line interface. [#fn1 (1)] For the purpose of maintaining disks we only need ssacli and perhaps ssaducli.

  • install the hp supported utilities.

letting the OS see the drives

Once we know what drives are available we can create logical drives which will be presented to the os (assuming the same set target command above) 

 => set target controller slot=0
 ...
 => create type=ld drives=3C:1:7 size=max raid=0  
 => create type=ld drives=3C:1:8 size=max raid=0
 quit

Preparing the drives for removal

Before removing a drive you should delete the logical disk that it is associated with.

 => set target controller slot=0
 ...
 => Array G delete

Increasing write performance

once we get a ups we should be able to use the controllers write cache safely.

 => controller slot=0 modify drivewritecache=enable

 Warning: Without the proper safety precautions, use of write cache on physical
          drives could cause data loss in the event of power failure.  To ensure
          data is properly protected, use redundant power supplies and
          Uninterruptible Power Supplies. Also, if you have multiple storage
          enclosures, all data should be mirrored across them. Use of this
          feature is not recommended unless these precautions are followed.

[=#fn1 1]) This was discovered after digging around for the perccli raid utilities provided by dell (officially supported only on commercial RPM based systems but installable using alien)

[=#fn2 2]) The biggest pain in the ass other than the weirdness with the public signature was that HP fucking rebranded the hpssacli to ssacli. Most of the good web info and hp docs still reference the old utility name (nothing else changed).
