similar to: Question: vxvm/dmp or zfs/mpxio

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

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

Hi, I''m aware that if we talking about DMP on Solaris the preferred way is to use MPxIO, still I have a question if any of you got any experience with ZFS on top of Veritas DMP? Does it work? Is it supported? Any real life experience/tests in this subject? Regards, sendai -- This message posted from opensolaris.org

Here is what I have configured: T2000 with OBP 4.28.6 2008/05/23 12:07 with 2 - 72 GB disks as the root disks OpenSolaris Nevada Build 91 Solaris Express Community Edition snv_91 SPARC Copyright 2008 Sun Microsystems, Inc.

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 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,

We are looking at the alternatives to VXVM/VXFS. One of the feature which we liked in Veritas, apart from the obvious ones is the ability to call the disks by name and group them in to a disk group. Especially in SAN based environment where the disks may be shared by multiple machines, it is very easy to manage them by disk group names rather than cxtxdx numbers. Does zfs offer such

Customer asks: Will SunCluster 3.2 support ZFS zpool created with MPxIO devices instead of the corresponding DID devices? Will it cause any support issues?

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

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

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

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, 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:

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

Hello list, I am using Samba with ADS authentication. I am able to map drives and open and close files with no issues with the exception of Microsoft Outlook email files. So from within Outlook, I open one of these email files and I get an access denied error. Even if i put 777 permission on the files in question I get the same error. I am using LDAP as a user and group store if that means
