similar to: ZFS zpool created with MPxIO devices question

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 HBA and external SATA

We have a Sun v890, and I''m interested converting existing ZFS zpool from c#t#d# to MPxIO. % zpool status pool: data state: ONLINE status: ONLINE scrub: scrub completed with 0 errors on Sun Jul 15 10:58:33 2007 config: NAME STATE READ WRITE CKSUM data ONLINE 0 0 0 mirror ONLINE 0 0 0 c1t2d0

Hello experts, My client 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.

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 OS so dev__pathname won''t be able to tell me per HBA i/O. Regds,

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 machine, I also have two NICs connected in

Hi, I have a customer that would like to open a RFE on the following issue... Describe the problem: It would be nice if zfs -H didn''t print any output to STDERR (or if there was some way to tell it not to). Given it''s for scripting mode, I''m going to be checking the return code anyway and doing something based on the return code not the string sent to STDERR.

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 device names (despite the fact

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

Greetings, In looking for inexpensive JBOD and/or RAID solutions to use with ZFS, I''ve run across the recent "VTrak" SAS/SATA systems from Promise Technologies, specifically their E-class and J-class series: E310f FC-connected RAID: http://www.promise.com/product/product_detail_eng.asp?product_id=175 E310s SAS-connected RAID:

Does opensolaris iSCSI target support SCSI-3 PGR reservation ? My goal is to use the iSCSI LUN created by [1] or [2] as a quorum device for a 3-node suncluster.

I''d like to keep the desired and current states of a machine regarding it''s configuration. Sometimes a chain of administrative commands is needed to get a special thing (re)configured on a machine, e.g. reconfig of a suncluster. This cannot be done with puppet in an easy way. In the majority of cases, these commands change appropriate files, which reflect the current

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:

Hello, I am trying to configure ZFS with IBM sdd. IBM sdd is like powerpath, MPXIO or VxDMP. Here is the error message when I try to create my pool: bash-3.00# zpool create tank /dev/dsk/vpath1a warning: device in use checking failed: No such device internal error: unexpected error 22 at line 446 of ../common/libzfs_pool.c bash-3.00# zpool create tank /dev/dsk/vpath1c cannot open

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 manages if we can avoid it. Has anyone

Hi everyone, Just wanted to tell you a little story. We''ve been enthusiastic puppet users since about a year ago here at the Geographic Institute of the University of Zürich. But we won''t use the zpool type ever again. Its just not worth it. Here''s what happened: . one of our servers lost knowledge about one of its zfs pools . puppet didn''t find the pool
