Hi there, I attempted some updates to my server this weekend, and things didn't go as planned. I'm hoping someone will be able to spot a hardware incompatibility, or user error.
What I started with:
I have a CSE-846 with BPN-SAS3-846EL1 backplane that has been working well for a year or so.
LSI SAS9340-8i it mode in CSE-846 -> 1m Mini SAS HD SFF-8643 cable -> BPN-SAS3-846EL1 -> ** Drives
What I want to do:
I'm attempting to connect the backplane in my CSE-846 to another server I added to my rack/discontinue use of the motherboard/cpu in the CSE-846.
The configuration I wanted:
LSI SAS9340-8i it mode in 3u case -> 1m Mini SAS HD SFF-8643 cable ->Mini SAS HD SFF-8644 to Internal SAS HD SFF-8643 adapter -> External Mini SAS HD SFF-8644 to Mini SAS HD SFF-8643 2m cable -> BPN-SAS3-846EL1 in CSE-846/4u case -> ** Drives
Parts I have been using for a year/known to work/are working in my current configuration below:
What happens:
The LSI SAS9340-8i can't find any drives when running in the desired configuration above.
Current configuration:
LSI SAS9340-8i it mode in 3u case -> 1m Mini SAS HD SFF-8643 cable -> BPN-SAS3-846EL1 in CSE-846/4u case -> ** Drives.
The current configuration is very undesirable. I have to unrack the servers so the 1m cable reaches, the servers can't be moved.
Does anyone see a compatibility issue on the configuration I am attempting?
is 3m just too long of a run for SFF-8643/SFF-8644 cables?
This is my first time using SFF-8644 cables, I could just be doing it wrong somehow I suppose. The cable seems snug though/I have to release the clip to remove it.
Thanks for your time, let me know if you see anything I should try/have a suggestion on other hardware to get this setup working (I don't want to buy a new backplane/enclosure, but a new sas 12 card with it mode, alternate cables/adapters, let me know what you suggest and I will give it a shot).
