Post subject: | F-Class Cabling Options |
Hi, This is my first post, so bear with me! I have inherited an F400 for my demo environment and I'm playing around with it. I had it up and running and started down a "I wonder what happens if..." route and decided to remove two of the shelves. The array had four shelves, all half-populated, so I removed two shelves and moved the disks to the remaining shelves. I changed the ID indicators on the shelves both to "1" and removed the loop - directly connecting each shelf to the first two ports on the FC card in slot 2. Magically, the array picked up the moved disks and works fine (which I didn't expect) but is now complaining about the lost loops which it sees as broken. Is there any way to repair this? From my training I seem to remember that direct-connecting shelves is supported on F-Class arrays with the downfall of the loss of host-ports, but with just two shelves this isn't really an issue for me. Thanks in advance |

Wow, I would have expected data loss, but your saying it recognized the drives and rolled with the change? Check out "help servicecage" and see if that has what you want. |

I didn't think the data would survive either - I was expecting all the VVs (including the admin volume) to be lost since two shelves were being removed, the array would have a wobbly when it started and run in what's essentially single-user mode. However, now I've run the command below the array is working perfectly, no data loss, no warnings, nothing. Thanks for the pointer, a quick... Code: servicecage remove cage1 servicecage remove cage3 ...removed both cages with a blue question mark next to them (I didn't need to prepare it since it was already gone) and now the errors have gone. |
