similar to: ZFS with Veritas DMP?

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

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 just deploy the ZFS on an SAN attach disk array and it''s working fine. How do i get dual pathing advantage of the disk ( like DMP in Veritas). Can someone point to correct doc and setup. Thanks in Advance. Rgds Vikash Gupta This message posted from opensolaris.org

Hi WizaRds, I tried reading the S-PLUS file ftp://ftp.research.att.com/dist/bayes-meta/hblm.dmp into R using data.restore("hblm.dmp") but I got an error: Error in attributes(value) <- thelist[-match(c(".Data", ".Dim", ".Dimnames", : row names must be 'character' or 'integer', not 'double' In

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:

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

I'm sorry that this question has been asked before but I ask it again because in the archives I didn't see a solution. It's an old S-plus dmp file for a hierarchical bayes linear model program written by DuMouchel and available publicly and freely at: ftp://ftp.research.att.com/dist/bayes-meta/hblm.dmp Only problem is that it cannot be read in R, even using the functions of the

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:

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

Where can I find a list of supported multipath drivers for ZFS?

hi all, I am hoping to move roughly 1TB of maildir format email to ZFS, but I am unsure of what the most appropriate disk configuration on a 3510 would be. based on the desired level of redundancy and usable space, my thought was to create a pool consisting of 2x RAID-Z vdevs (either double parity, or single parity with two hot-spares). using 300GB drives this would give roughly 2.4TB of usable

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

I''ve hit this bug on four of my Solaris 11 servers. Looking for anyone else who has seen it, as well as comments/speculation on cause. This bug is pretty bad. If you are lucky you can import the pool read-only and migrate it elsewhere. I''ve also tried setting zfs:zfs_recover=1,aok=1 with varying results. http://docs.oracle.com/cd/E26502_01/html/E28978/gmkgj.html#scrolltoc

Hi, I am running RH 7.2 (professional release 2.4 kernel) I have a ext3 file system which stores large oracle "dump files" over 4GB. We write to it via NFS which is working great, the problem is when we issue a file largefile.dmp from the linux box it fails on anything over 4GB stating that can't stat 'largefile.dmp' (value too large for defined data type). We can do
