DRD with SmartArray controller ?

[mst]

Hello,

i have a rx2660 with 11.23 installed.
All the HDD's are connected to a SmartArray Controller, which gives me the following output from saconfig:

---------- PHYSICAL DRIVES ----------

As you can see, bay 3 has an unassigned disk with 146 GB, i would like to use this with DRD.

The OS is installed on the two 73.4 GB disks, so i assume disk space should not be the problem, but is DRD able to use the disk which is connected to the raid controller for creating the clone ?

Hi,

DRD doesnt have any special features. DRD can only see the disks which is detected by OS.

You may need to use this disk and create a new RAID volume. Once it is visible in "ioscan"

you can use

#drd clone -t disk

Hello,

thank you for your answer. I may give it a try as you suggested, but meanwhile, while reading some of the drd manuals, another question comes up to me:

They say one must use the command "drd activate" in order to tell the server to use the DRD image the next time the server boots.

But of course i can only do this while the server is still up and running.

If (for any reason) i reboot my server and run into trouble (server won't boot...), will the (inactive) drd image be of any use ? is there anyway i can activate it when i'm not able to boot the server ?

Looks like "drd activate" essentially just runs the "setboot" command for you, determining the correct parameters automatically.

If you change the boot settings using EFI (or PDC in PA-RISC systems), it should be fully equivalent of using the "drd activate" command.

Hi,


Simple, just set the boot path manually from EFI and boot from the disk which you have used for cloning.

Hello, thank you very much.

Meanwhile i run into the problem that i cannot make a device file for this single unassigned disk, as it seems to me that saconfig always wants to have a minimum of 2 disks...

But thank you for your efforts anyway.
