I understand and agree ;-) |

I will consider this ... |
| 43 |
|
| 44 |
As I understand things here: |
| 45 |
|
| 46 |
the former admin *tried to* setup multipath and somehow got stuck. |
| 47 |
That's why it isn't running and not used at all. He somehow mentioned |
| 48 |
this in an email back then when he was still working there. |
| 49 |
|
| 50 |
So currently it seems to me that the storage is attached via "single |
| 51 |
path" (is that the term here?) only. "directly"= no redundancy |
| 52 |
|
| 53 |
That means using the lpfc-kernel-module to run the FibreChannel-adapters |
| 54 |
... which failed to come up / sync with a more recent gentoo kernel, as |
| 55 |
initially mentioned. |
| 56 |
|
| 57 |
(right now: 4.1.15-gentoo-r1 ... ) |
| 58 |
|
| 59 |
I consider sending a Debian-OS on a SSD there and let the (low |
| 60 |
expertise) guy there boot from it. (or a stick). Which in fact is risky |
| 61 |
as he doesn't know anything about linux. |
| 62 |
|
| 63 |
Or I simply wait for my on-site-appointment and start testing when I am |
| 64 |
there. |
| 65 |
|
| 66 |
Maybe I am lucky and the debian lpfc stuff works from the start. And |
| 67 |
then I could test multipath as well. |
| 68 |
|
| 69 |
I assume that maybe the adapters need a firmware update or so. |

The current gentoo installation was done with "hardened" profile, not |
| 74 |
touched for years, no docs .... so it somehow seems way too much hassle |
| 75 |
to get it up to date again. Additionally no experts on site there, so it |
| 76 |
should be low maintenance anyway. |
