Re: [OpenIndiana-discuss] Only one SSD detected on expander
The need of (different) WWN on Sata SSDs seems quite new for some Vendors. I have had the same problem with a couple of SSDs (Winkom Pro) that I bought recently. Winkom was very helpful to fix the problem with newer SSDs and i was able to send them back for SSD's that have a firmware with unique WWN.

So one more data point that seems to suggest that I'm getting duplicate names from these drives. When I attach at least one of the Samsung SSDs to each expander (front and back), I get this: $ cfgadm -al Ap_Id Type Receptacle Occupant Condition c6 scsi-sas connectedconfigured unknown c6::es/ses0ESI connectedconfigured unknown c6::smp/expd0 smp connectedconfigured unknown c6::w5002538043584d30,0disk-pathconnectedconfigured unknown -- SSD c6::w5000c500513a0efe,0disk-pathconnectedconfigured unknown c6::w5000c5005168b2f0,0disk-pathconnectedconfigured unknown c6::w5000c5005169a612,0disk-pathconnectedconfigured unknown c6::w5000c5005169cc6a,0disk-pathconnectedconfigured unknown c6::w5000c500515199bd,0disk-pathconnectedconfigured unknown c6::w5000c500517042d9,0disk-pathconnectedconfigured unknown c8 scsi-sas connectedconfigured unknown c8::es/ses1ESI connectedconfigured unknown c8::smp/expd1 smp connectedconfigured unknown c8::w5002538043584d30,0disk-pathconnectedconfigured unknown -- SSD c9 scsi-sas connectedunconfigured unknown sata0/0::dsk/c4t0d0disk connectedconfigured ok sata0/1::dsk/c4t1d0disk connectedconfigured ok sata0/2sata-portemptyunconfigured ok sata0/3sata-portemptyunconfigured ok sata0/4sata-portemptyunconfigured ok sata0/5sata-portemptyunconfigured ok Note that both c6 and c8 have the exact same name for these drives.

Thanks. -Scott On Oct 16, 2012, at 7:29 PM, Scott Marcy o...@mscott.org wrote: Hi all, I'm new to the list and OI, but I've been running a Solaris box with some version of ZFS on it for a couple years. I recently acquired a Supermicro 6047R-E1R36N. It has an X9DRi-LN4F+ motherboard, dual E5-2620s and 48GB of RAM. I soon learned that I needed a different HBA (it comes with an LSI 2108-based card that doesn't have any JBOD passthrough mode), so I replaced that with an LSI SAS9211-8i, flashed with the latest IT firmware. Being new to SAS expanders (which this server has two of), I quickly learned that some older 2TB drives I had on my older Solaris box simply will not work reliably on the expander. (They would very quickly lock up the entire file system once the load got heavy.) However, I've had much better luck (so far) with some newer 3TB SATA drives (Seagate ST3000DM001). I'm still not convinced that these are going to be reliable in the long run, having now read about a few SATA-on-SAS expander horror stories (and my own experience with the 2TB drives), but this isn't a production system (yet) so I'm willing to see how it goes. But the one problem I can't seem to figure out are the Samsung 830 SSD drives I have for ZIL and ARC. I have 2 mirrored 128GB 830s as the boot pool, but they're on the built-in SATA ports, not the expander ports. Then I have four other 128GB 830s which I installed into 3.5 hot-swap adapters and these are the ones causing problems. The HBA sees the drives just fine—they're listed during POST and I can access them via the card's built-in BIOS. But once OI (151a5) is up and running, it only sees ONE of the 830s. And here's where it gets weird: if I remove all but one of the SSDs from the expander ports, it will see whichever one SSD is connected—it does not matter which port the drives are on. Also, regardless of the port, the attachment path always seems to be the same in the OS. It's like the OS thinks all four drives are the exact same physical drive. $ cfgadm -al Ap_Id Type Receptacle Occupant Condition c6 scsi-sas connectedconfigured unknown c6::es/ses0ESI connectedconfigured unknown c6::smp/expd0 smp connectedconfigured unknown c6::w5002538043584d30,0disk-pathconnectedconfigured unknown -- this is the SSD c6::w5000c500513a0efe,0disk-pathconnectedconfigured unknown c6::w5000c5005168b2f0,0disk-pathconnectedconfigured unknown c6::w5000c5005169a612,0disk-pathconnectedconfigured unknown c6::w5000c5005169cc6a,0disk-pathconnectedconfigured unknown c6::w5000c500515199bd,0

Re: [OpenIndiana-discuss] Only one SSD detected on expander
SATA devices are not required to provide a WWN - I would guess that they're providing the same WWN, and as a result, your SAS devices are becoming sad. If you could tell the expander(s) to ignore that and assign one, that'd be neat. If there's a firmware update to fix it, even better. If you want to shell out for SAS - SATA interposers, that would probably also solve it, though I can't swear to anything, but that'd probably be more expensive than returning + replacing the SSDs. Don't know.

(He did seem to understand what I was talking about, which was actually more than I expected from simply picking up the phone and getting transferred twice to get to the right department. So at least kudos to Samsung there.) He did suggest that maybe the new 840 Pros might work, and he was going to check to see if they report unique WWNs or not. Since those don't appear to be shipping yet, I don't have any way of finding out myself, but if anybody is interested, I can pass along what Samsung says when (if) they get back to me on the 840 Pro.

Yes, all the drives report the same LU WWN Device Id in smartctl, and I see the same constant WWN reported online (for example, http://blog.gmane.org/gmane.linux.utilities.smartmontools.database/page=7). I'll see what Samsung has to say. Thanks!

If you could tell the expander(s) to ignore that and assign one, that'd be neat. If there's a firmware update to fix it, even better. If you want to shell out for SAS - SATA interposers, that would probably also solve it, though I can't swear to anything, but that'd probably be more expensive than returning + replacing the SSDs. Don't know. If it were me, I'd complain to Samsung support and see what you got back. - Rich On Wed, Oct 17, 2012 at 11:13 AM, Scott Marcy o...@mscott.org wrote: Well, I enabled multipath support with 'stmsboot -e -D mpt' and rebooted and now it seems I have two paths to what is no doubt two physical devices: $ mpathadm list LU /dev/rdsk/c7t5002538043584D30d0s2 Total Path Count:

Re: [OpenIndiana-discuss] Only one SSD detected on expander
I am returning the 4 drives I planned to use in the expanders, but will keep the two I'm using as my mirrored boot pool. My intention was to use these are ZIL and L2ARC drives, so I can do without them for now. I've had very good luck with these Samsung drives in non-SAS usages—quite a bit more reliable in my (admittedly quite limited) experience than the SanForce-based SSDs. Here's hoping they've fixed this on the 840 Pro models. Thank you all for your help. I learned something new and now understand why it doesn't work. :-) -Scott On Oct 17, 2012, at 11:18 AM, Bob Friesenhahn bfrie...@simple.dallas.tx.us wrote: On Wed, 17 Oct 2012, Scott Marcy wrote: I called Samsung and they basically told me there was nothing they could do.

[OpenIndiana-discuss] Only one SSD detected on expander
Hi all, I'm new to the list and OI, but I've been running a Solaris box with some version of ZFS on it for a couple years. I recently acquired a Supermicro 6047R-E1R36N. It has an X9DRi-LN4F+ motherboard, dual E5-2620s and 48GB of RAM. I soon learned that I needed a different HBA (it comes with an LSI 2108-based card that doesn't have any JBOD passthrough mode), so I replaced that with an LSI SAS9211-8i, flashed with the latest IT firmware. Being new to SAS expanders (which this server has two of), I quickly learned that some older 2TB drives I had on my older Solaris box simply will not work reliably on the expander. (They would very quickly lock up the entire file system once the load got heavy.) However, I've had much better luck (so far) with some newer 3TB SATA drives (Seagate ST3000DM001). I'm still not convinced that these are going to be reliable in the long run, having now read about a few SATA-on-SAS expander horror stories (and my own experience with the 2TB drives), but this isn't a production system (yet) so I'm willing to see how it goes. But the one problem I can't seem to figure out are the Samsung 830 SSD drives I have for ZIL and ARC. I have 2 mirrored 128GB 830s as the boot pool, but they're on the built-in SATA ports, not the expander ports. Then I have four other 128GB 830s which I installed into 3.5 hot-swap adapters and these are the ones causing problems. The HBA sees the drives just fine—they're listed during POST and I can access them via the card's built-in BIOS. But once OI (151a5) is up and running, it only sees ONE of the 830s. And here's where it gets weird: if I remove all but one of the SSDs from the expander ports, it will see whichever one SSD is connected—it does not matter which port the drives are on. Also, regardless of the port, the attachment path always seems to be the same in the OS. It's like the OS thinks all four drives are the exact same physical drive. $ cfgadm -al Ap_Id Type Receptacle Occupant Condition c6 scsi-sas connectedconfigured unknown c6::es/ses0ESI connectedconfigured unknown c6::smp/expd0 smp connectedconfigured unknown c6::w5002538043584d30,0disk-pathconnectedconfigured unknown -- this is the SSD c6::w5000c500513a0efe,0disk-pathconnectedconfigured unknown c6::w5000c5005168b2f0,0disk-pathconnectedconfigured unknown c6::w5000c5005169a612,0disk-pathconnectedconfigured unknown c6::w5000c5005169cc6a,0disk-pathconnectedconfigured unknown c6::w5000c500515199bd,0disk-pathconnectedconfigured unknown c6::w5000c500517042d9,0disk-pathconnectedconfigured unknown c8 scsi-sas connectedconfigured unknown c8::es/ses1ESI connectedconfigured unknown c8::smp/expd1 smp connectedconfigured unknown c9 scsi-sas connectedunconfigured unknown sata0/0::dsk/c4t0d0disk connectedconfigured ok sata0/1::dsk/c4t1d0disk connectedconfigured ok sata0/2sata-portemptyunconfigured ok sata0/3sata-portemptyunconfigured ok sata0/4sata-portemptyunconfigured ok sata0/5sata-portemptyunconfigured ok $ format Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c4t0d0 ATA-SAMSUNGSSD830-3B1Q cyl 19932 alt 2 hd 224 sec 56 /pci@0,0/pci15d9,626@1f,2/disk@0,0 1. c4t1d0 ATA-SAMSUNGSSD830-3B1Q cyl 19932 alt 2 hd 224 sec 56 /pci@0,0/pci15d9,626@1f,2/disk@1,0 2. c7t5000C500513A0EFEd0 ATA-ST3000DM001-9YN1-CC4B-2.73TB /scsi_vhci/disk@g5000c500513a0efe 3. c7t5000C5005168B2F0d0 ATA-ST3000DM001-9YN1-CC4B-2.73TB /scsi_vhci/disk@g5000c5005168b2f0 4. c7t5000C5005169A612d0 ATA-ST3000DM001-9YN1-CC4B-2.73TB /scsi_vhci/disk@g5000c5005169a612 5. c7t5000C5005169CC6Ad0 ATA-ST3000DM001-9YN1-CC4B-2.73TB /scsi_vhci/disk@g5000c5005169cc6a 6. c7t5000C500515199BDd0 ATA-ST3000DM001-9YN1-CC4B-2.73TB /scsi_vhci/disk@g5000c500515199bd 7. c7t5000C500517042D9d0 ATA-ST3000DM001-9YN1-CC4B-2.73TB /scsi_vhci/disk@g5000c500517042d9 8. c7t5002538043584D30d0 ATA-SAMSUNG SSD 830-3B1Q-119.24GB /scsi_vhci/disk@g5002538043584d30 This last one is the SSD.
