Firstly, just to let you know, the chassis SC5400LX can support two backplanes: one 6 drive cage and one 4 drive cage.
SC5400Base can support only one backplane.
Before doing any test, i always advise to make sure to have a complete verified and separate backup as a precaution measure.
Now regarding your question:
Yes, it should be alright to transfer the 4 drives to the new 6 drive cage.
Since the new backplane is also an expander backplen, i will advise you to update the HSC firmware for the new expander 6 drive cage backplane.
And when moving the drives, it is best that the drives are inserted in the same slot position as they were in the previous 4 drive backplane.
Other than this, i think it should be alright. I have done this several times on my PSLSATA system.
All the best,
Thanks Aryan, everything worked as you said.
However, I had a problem with RedHat Linux v4.6 and the 6 drive cage. The array was recognized and the status showed online. The os would boot, but the Linux driver could not find the disk array and the kernel panicked. I switched back to the 4 drive cage and no problem.
This is NOt a new install. It is a migration from a 4 drive extender backplane to a 6 drive extender backplane. Linux uses the virtual drive created by ESRT2, it doesn't "know" about the RAID array.
The custom web application in use does not support Rehat v5, so I can't upgrade the OS.
What exactly is the "HSC firmware"? What does "HSC" stand for? I've looked in the download section and there is no reference to it.
Yes. HSC stands for Hot swap controller.
issue this cmd to find the HSC version.
cmdtool c0 18 01
cmdtool c2 18 01...(depending on whether primary or secondary HSC)
Depending on where you have connected the HSC....on the motherboard......HSBPA or HSBPB....anyway...you can give both the commands and see the response..
Ok. let me reiterate your issue to understand better.
You were able to install RHEL 4.6 in 4 cage and when you tried to migrate to 6 Cage, kernel panic occured. but array was recognised and status showed online.
(did i understand your issue better?)
