similar to: LSI 3GB HBA SAS Errors (and other misc)

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

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, Has anyone out there been able to qualify the Proliant DL360 G7 for your Solaris/OI/Nexenta environments? Any pros/cons/gotchas (vs. previous generation HP servers) would be greatly appreciated. Thanks in advance! -Anh

I know that this has been well-discussed already, but it''s been a few months - WD caviars with mpt/mpt_sas generating lots of retryable read errors, spitting out lots of beloved " Log info 31080000 received for target" messages, and just generally not working right. (SM 836EL1 and 836TQ chassis - though I have several variations on theme depending on date of purchase: 836EL2s,

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

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

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:

Hi, I know (from the zfs-discuss archives and other places [1,2,3,4]) that a lot of people are looking to use zfs as a storage server in the 10-100TB range. I''m in the same boat, but I''ve found that hardware choice is the biggest issue. I''m struggling to find something which will work nicely under solaris and which meets my expectations in terms of hardware.

Hi guys! Unfortunately there is no offtopic list but the subject is somehow related to centos as the OS is/will be centos :) So, under this thin cover i ask : Is it possible that for a SAS controler like LSI 3008 that in specs says that : "This high-performance I/O controller supports T-10 data protection model and optical support, PCIe hot plugging, and up to 1,000 connected devices"

Dear All, It may be this not the correct mailing list, but I''m having a ZFS issue when a disk is failing. The system is a supermicro motherboard X8DTH-6F in a 4U chassis (SC847E1-R1400LPB) and an external SAS2 JBOD (SC847E16-RJBOD1). It makes a system with a total of 4 backplanes (2x SAS + 2x SAS2) each of them connected to a 4 different HBA (2x LSI 3081E-R (1068 chip) + 2x LSI

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

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

I want to configure my zfs like this : concatination_stripe_pool : concatination lun0_controller0 lun1_controller0 concatination lun2_controller1 lun3_controller1 1. There is any option to implement it in ZFS? 2. there is other why to get the same configuration? thanks This message posted from opensolaris.org

My setup: A SuperMicro 24-drive chassis with Intel dual-processor motherboard, three LSI SAS3081E controllers, and 24 SATA 2TB hard drives, divided into three pools with each pool a single eight-disk RAID-Z2. (Boot is an SSD connected to motherboard SATA.) This morning I got a cheerful email from my monitoring script: "Zchecker has discovered a problem on bigdawg." The full output is

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 posted a thread on this once long ago[1] -- but we''re still fighting with this problem and I wanted to throw it out here again. All of our hardware is from Silicon Mechanics (SuperMicro chassis and motherboards). Up until now, all of the hardware has had a single 24-disk expander / backplane -- but we recently got one of the new SC847-based models with 24 disks up front and 12 in the

Hi all, I recently experienced a disk failure on my home server and observed checksum errors while resilvering the pool and on the first scrub after the resilver had completed. Now everything seems fine but I''m posting this to get help with calming my nerves and detect any possible future faults. Lets start with some specs.

Hi all; We have a Solaris 10 U9 x86 instance running on Silicon Mechanics / SuperMicro hardware. Occasionally under high load (ZFS scrub for example), the box becomes non-responsive (it continues to respond to ping but nothing else works -- not even the local console). Our only solution is to hard reset after which everything comes up normally. Logs are showing the following: Jan 8
