We''re currently designing a ZFS fileserver environment with iSCSI based storage (for failover, cost, ease of expansion, and so on). As part of this we would like to use multipathing for extra reliability, and I am not sure how we want to configure it. Our iSCSI backend only supports multiple sessions per target, not multiple connections per session (and my understanding is that the

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

Please reply to david.curtis at sun.com ******** Background / configuration ************** zpool will not create a storage pool on fibre channel storage. I''m attached to an IBM SVC using the IBMsdd driver. I have no problem using SVM metadevices and UFS on these devices.

Dear all Sorry if it''s kind of off-topic for the list but after talking to lots of vendors I''m running out of ideas... We are looking for JBOD systems which (1) hold 20+ 3.3" SATA drives (2) are rack mountable (3) have all the nive hot-swap stuff (4) allow 2 hosts to connect via SAS (4+ lines per host) and see all available drives as disks, no RAID volume. In a

Dear all, i've appended the below to /etc/bashrc it works like a charm with ssh connections though SFTP sessions fail since the below is being sent to the intiator. any way of limiting the below to none sftp sessions? or any other idea for it to work? # If id command returns zero, you?ve root access. if [ $(id -u) -eq 0 ]; then # you are root, set red colour prompt echo

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

Hello I'm using your program R in a course I'm taking at the University of Oslo, and thereby I need to download it to my PC. Unfortunately I do have some problems, I do not know whish files to download and how I do it. Can you please send me a list of what to download and a like where to find it? Thanks a lot, best regards Maria Befring Hovda PhD-student Norconserv AS, Seafood

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:

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

I have an iscsi array that I'd like to mount and share using NFS and I need it to happen without user intervention on a reboot. In the default configuration this doesn't seem to work very well because the iscsi intiator isn't started until after the network is up (obviously) and by that time all local filesystems are mounted. I can't mount the partitions in rc.local because NFS

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

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 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've Vista64 accessible from Suse11 and would like to start my installed windows programs also from Suse. -How should I update? Wait for the 64bit Wine? -How could I use the programs, dlls etc all from Vista64? Any program for a such wine config? Thanks and regards Michael

Hi, we have SunFire X4140 connected to Dell MD1220 SAS enclosure, single path, MPxIO disabled, via LSI SAS9200-8e HBA. Disks are visible with sas-addresses such as this in "zpool status" output: NAME STATE READ WRITE CKSUM cuve ONLINE 0 0 0 mirror-0 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,
