ZFS vs mpxio vs cfgadm in Solaris.
Folks, I''m trying to figure out whether we should give ZFS / mpxio a shot on one of our research servers, or simply skip it (as we have previously). In Nov 2009 Cindy responded to a thread concerning ZFS device issues, cfgadm, and mpxio: http://mail.opensolaris.org/pipermail/zfs-discuss/2009-November/033496.html I''ve got an x2270 with the Sun EZ-SAS H...

Using zfs boot with MPxIO on T2000
...ated a zfs mirror of the root disk c0t0d0 to c0t1d0, format shows the mirrored disk with sectors instead of cylinders, is this normal or correct? Is there a way to reverse this back to cylinders if it is not? Same goes for the external disk pool using SAN disk from the IBM SVC. 2. After enabled MPxIO (stmsboot -e), the 2 root disks now have MPxIO labels, is this a bug with ZFS boot using MPxIO? I have MPxIO running on Solaris 10 release 4 with none of this behavior (I have 2 T2000''s, 1 with SVM root disks and other with Veritas Encapsulated root disks, all external or non root filesys...

Desperate question about MPXIO with ZFS-iSCSI
I''m trying to set up a iscsi connection (with MPXIO) between my Vista64 workstation and a ZFS storage machine running OpenSolaris 10 (forget the exact version). On the ZFS machines, I have two NICS. NIC #1 is 192.168.1.102, and NIC #2 is 192.168.2.102. The NICs are connected to two separate switches serving two separate IP spaces. On my Vista64 ma...

Question: vxvm/dmp or zfs/mpxio
...is thinking about changing one of their servers running Solaris 8 (NIS Hub to mention something) to a server running Solaris 10. The question that i have given is to check the differences or if you wish the status/stability of changing VXvm with DMP (Dynamic Multi Pathing) to a system with ZFS and MPXio. I have made my share of RTFM but not come any closer to an answer. So now i am turning to you guys! Is ZFS/mpxio strong enough to be an alternativ to VXvm/Dmp today? Has anyone done this change and if so, what was your experiance? Regards, Pierre This message posted from opensolaris.org

Re: Difference between ZFS and UFS with one LUN froma SAN
This may not be the answer you''re looking for, but I don''t know if it''s something you''ve thought of. If you''re pulling a LUN from an expensive array, with multiple HBA''s in the system, why not run mpxio? If you ARE running mpxio, there shouldn''t be an issue with a path dropping. I have the setup above in my test lab and pull cables all the time and have yet to see a zfs kernel panic. Is this something you''ve considered? I haven''t seen the bug in question, but I defin...

Experience with Promise Tech. arrays/jbod''s?
...If you''re using dual RAID controllers with SATA drives, they sell a dual-port adapter that goes in the canister with each disk drive. Has anyone tried these with Solaris yet? The docs claim Solaris-ready, but I''m particularly curious to know if the E310f supports Sun''s MPXIO (multipathing) drivers in the dual-controller configuration. How about the SAS-connected chassis''? What SAS HBA''s are people using with Solaris-10? I''m mostly hoping to hear if these products are decent, or junk, or somewhere in between. Thanks and regards, Marion

mpt_sas multipath problem?
Greetings, We''re trying out a new JBOD here. Multipath (mpxio) is not working, and we could use some feedback and/or troubleshooting advice. The OS is oi151a7, running on an existing server with a 54TB pool of internal drives. I believe the server hardware is not relevant to the JBOD issue, although the internal drives do appear to the OS with multipath dev...

Dtrace + mpxio
Hi ! I am using MPXIO for doing multipathing across four HBA''s. Now I need to know how much IO/sec each HBA card is serving. With EMC powerpath installed, we could get this using powermt display every=5. is there any way I can use Dtrace to extract this output ? I guess MPXIO just shows one Device name to the O...

ZFS and powerpath
How much fun can you have with a simple thing like powerpath? Here''s the story: I have a (remote) system with access to a couple of EMC LUNs. Originally, I set it up with mpxio and created a simple zpool containing the two LUNs. It''s now been reconfigured to use powerpath instead of mpxio. My problem is that I can''t import the pool. I get: pool: ###### id: ################### state: FAULTED status: One or more devices are missing from the syste...

using veritas dmp with ZFS (but not vxvm)
We have some HDS storage that isn''t supported by mpxio, so we have to use veritas dmp to get multipathing. Whats the recommended way to use DMP storage with ZFS. I want to use DMP but get at the multipathed virtual luns at as low a level as possible to avoid using vxvm as much as possible. I figure theres no point in having overhead from 2 volume man...

LSI 3GB HBA SAS Errors (and other misc)
During the diagnostics of my SAN failure last week we thought we had seen a backplane failure due to high error counts with ''lsiutil''. However, even with a new backplane and ruling out failed cards (MPXIO or singular) or bad cables I''m still seeing my error count with LSIUTIL increment. I''ve got no disks attached to the array right now so I''ve also ruled those out. Even with nothing connected but the HBA to the backplane expander, a simple restart of the SAN into a OpenI...
