Only one of three SATA drives detected

[prior_philip]

Dear all,
I planned a drive replacement in the 4 bay hdd case which is connected to a N54 HP Microserver G3 via SATA cable.
First I updated from 11-stable to 11.2-U6, works fine after a few hickups.
Configuration:
HP Microserver G3 n54 with 4x4TB drives in RAIDZ1
Silverstone 4 bay case with 4x 2tb HDDs attached via SATA to HD MicroServer, configured as a second RAIDZ1 pool

Since upgrading to 11.2 only one disk in this external HDD case is detected when connecting via SATA. When connecting with USB all four are detected but serialnumber are reported as 000000000000 and they gets detached.

Is there something that I can do to solve this?

Have a look at the output of gmultipath list

 

[prior_philip]

gmultipath list does not give back anything.

Show : gmultipath list

newton# gmultipath list

But camcontrol devlist:
As you see, last entry only lists one 6GB drive. 3 are docked into the case.

Show : camcontrol devlist

I had thought it may be multipath hiding the additional drives as some external cases don't support bifurcation.

It may come down to the external case not supporting the pass-through of multiple drives.

 

[prior_philip]

Well it even didnt list the internal drives.....

 

[sretalla]

That's normal, gmultipath only lists drives that are found via complex controller setup, simple SATA port connections won't appear there.

 

[prior_philip]

Strange behavior. W10 reads the drives out correctly but FreeNAS doesnt. Is there an eSATA diagnostic tool available or any kernel debug messages Im not aware of?

 

[sretalla]

That will be because the driver in Windows 10 can handle the port multiplier feature which does the bifurcation.

I don't think the FreeBSD driver will give you a lot of help with that.

As a general rule, eSATA enclosures aren't a great idea for FreeNAS.

Was the Silverstone case working previously under FreeNAS 11-stable?

 

[prior_philip]

Yes. since upgrade to 11.2 the drives are not recognized correctly

 

[HoneyBadger]

I wonder if there might have been a driver rollback in ahci or ada in upstream FreeBSD that would cause port multiplication to be unsupported or broken on your specific chipset.

If possible I would suggest filing a bug report with iXsystems through the Jira tracker and then rolling back to an 11.1 based build.

 

[prior_philip]

It seems server BIOS has been set back to default, so Multipath has been disabled.
11.2 now detects the drives in external disk cage.

Another question:
I had a RAIDZ1 pool inside the server which I like to move to the external disk cage, the drive numbers would change. How can I tell the pool to look for ada4-da07 instead of ada0-ada03 for example?
