similar to: ZFS vs mpxio vs cfgadm in Solaris.

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

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

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.

We recently upgraded last week to OpenSolaris Development snv_128a and all things went fine, zpool still works, etc. Our disks come off a Hitachi Disk Array and we have 2 qLogic fiber cards in our server. "cfgadm -al" use to report the cards and "luxadm probe" use to return all the disks on the array. "luxadm probe" now returns "ERROR: No Fibre Channel Adapters

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 all, Can anyone explain to me, or point me to any docs that explain how the following numbers map together? I have multiple LUNS exported to my HBA''s from multiple EMC arrays. zpool status, and /dev/dsk show device names like: c0t6006048000038794003753594D333837d0 ONLINE 0 0 0 c0t6006048000038794003753594D333838d0 ONLINE 0 0 0

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

hello, all I am have constraint disk space (only 8GB) while running os inside vm. Now i want to add more. It is easy to add for vm but how can i update fs in os? I cannot use autoexpand because it doesn''t implemented in my system: $ uname -a SunOS sopen 5.11 snv_111b i86pc i386 i86pc If it was 171 it would be grate, right? Doing following: o added new virtual HDD (it becomes

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?

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:

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:

Hello, I am trying to configure ZFS with IBM sdd. IBM sdd is like powerpath, MPXIO or VxDMP.
