I'm working on building out a system for my home lab. I'll admit the use of a shelf as a JBOD via HBA is new to me as is the NetApp in general. Please forgive any naivety on my part - this is intended to be a learning experience for myself. I've been leveraging the best of my google-fu since Wednesday and here is where I'm at:
The hardware specs are as follows:
Server blade:
Dell Poweredge R610
2x Xeon E5620
192 GB RAM
2x136 HDDs in JBOD (FreeNAS-11.2-U7 is installed here and manages the two as RAIDz1)
Dell H200E HBA
NetApp DS2246:
20x 1.6 TB NetApp HDD (da4-da23;da28-da47)
4x ~600 GB NetApp SSD (da0-da3;da24-da27)
2x FAS2552 controllers
1. The FAS2552 controllers are connected to the Dell 200E HBA via a QSFP+ to SFF-8088 cable.
2. The Dell has no problem seeing the disks in the NetApp.
3. I was able to run sg_format to resize the HDDs in the NetApp and create a RAIDz2 pool on the 20x HDDs.
4. FreeNAS sees /dev/multipath/diskX for the HDDs but not the SSDs. gmultipath status output shows the same.
5. The output of sg_format -v --format --size=512 --six /dev/da0 shows:
camcontrol shows the following UUID pairings between the following pairs:
da0,da24
da1,da25
da2,da26
da3,da27
Attempting to run gmultipath label -v disk21 /dev/da0 /dev/da24 results in the following output:
dd attempts with if=/dev/zero result in an Invalid argument error being thrown. /dev/null does not throw an error.
All of the above commands fail in the same way with any of the SSD /dev/daX's.
I'm out of ideas at this point and I have exhausted all references available to me at this point. Please let me know if you require any additional information and I'll be happy to provide it.
