I''m testing an Iscsi multipath configuration on a T2000 with two disk devices provided by a Netapp filer. Both the T2000 and the Netapp have two ethernet interfaces for Iscsi, going to separate switches on separate private networks. The scsi_vhci devices look like this in `format'': 1. c4t60A98000433469764E4A413571444B63d0 <NETAPP-LUN-0.2-50.00GB>

I''ve got a zpool that has 4 raidz2 vdevs each with 4 disks (750GB), plus 4 spares. At one point 2 disks failed (in different vdevs). The message in /var/adm/messages for the disks were ''device busy too long''. Then SMF printed this message: Nov 23 04:23:51 x.x.com EVENT-TIME: Fri Nov 23 04:23:51 EST 2007 Nov 23 04:23:51 x.x.com PLATFORM: Sun Fire X4200 M2, CSN:

Sorry for the long post but I know trying to decide on hardware often want to see details about what people are using. I have the following AS-2022G-URF machine running OpenGaryIndiana[1] that I am starting to use. I successfully transferred a deduped zpool with 1.x TB of files and 60 or so zfs filesystems using mbuffer from an old 134 system with 6 drives - it ran at about 50MB/s or

Hi, I hope there''s someone here who can possibly provide some assistance. I''ve had this read problem now for the past 2 months and just can''t get to the bottom of it. I have a home snv_111b server, with a zfs raid pool (4 x Samsung 750GB SATA drives). The motherboard is a ASUS M2N68-CM (4 SATA ports) with an Athlon LE1620 single core CPU and 4GB of RAM. I am using it

On a V240 running s10u4 (no additional patches), I had a pool which looked like this: <pre> > # zpool status > pool: pool01 > state: ONLINE > scrub: none requested > config: > > NAME STATE READ WRITE CKSUM > pool01 ONLINE 0 0 0 > mirror

Hi, My solaris storage hangs. I login to the console and there is messages[1] display on the console. I can''t login into the console and seems the IO is totally blocked. The system is solaris 10u8 on Dell R710 with disk array Dell MD3000. 2 HBA cable connect the server and MD3000. The symptom is random. It is very appreciated if any one can help me out.

Please check whether you have latest '' MPT '' patch installed on your server ? If not , please install MPT patch . It will fix the issue . Regards, Gowrisankar .

In my new oracle server, sol11exp, it''s using multipath device names... Presently I have two disks attached: (I removed the other 10 disks for now, because these device names are so confusing. This way I can focus on *just* the OS disks.) 0. c0t5000C5003424396Bd0 <SEAGATE-ST32000SSSUN2.0-0514 cyl 3260 alt 2 hd 255 sec 252> /scsi_vhci/disk at g5000c5003424396b

Hi all, we have just bought a sun X2200M2 (4GB / 2 opteron 2214 / 2 disks 250GB SATA2, solaris 10 update 4) and a sun STK 2540 FC array (8 disks SAS 146 GB, 1 raid controller). The server is attached to the array with a single 4 Gb Fibre Channel link. I want to make a mirror using ZFS with this array. I have created 2 volumes on the array in RAID0 (stripe of 128 KB) presented to the host

Hi! I have a problem with ZFS and most likely the SATA PCI-X controllers. I run opensolaris 2008.11 snv_98 and my hardware is Sun Netra x4200 M2 with 3 SIL3124 PCI-X with 4 eSATA ports each connected to 3 1U diskchassis which each hold 4 SATA disks manufactured by Seagate model ES.2 (500 and 750) for a total of 12 disks. Every disk has its own eSATA cable connected to the ports on the PCI-X

Pre-fletching on the file and device level has been disabled yielding good results so far. We''ve lowered the number of concurrent ios from 35 to 1 causing the service times to go even lower (1 -> 8ms) but inflating actv (.4 -> 2ms). I''ve followed your recommendation in setting primarycache to metadata. I''ll have to check with our tester in the morning if it made

I''m running into a issue where there seems to be a high number of read iops hitting disks and physical free memory is fluctuating between 200MB -> 450MB out of 16GB total. We have the l2arc configured on a 32GB Intel X25-E ssd and slog on another32GB X25-E ssd. According to our tester, Oracle writes are extremely slow (high latency). Below is a snippet of iostat: r/s w/s

Not sure where to put this but I am cc''ing the ZFS - discussion board. I was successfull in creating iscsi shares using ZFS set shareiscsi=on with 2 thin provisioned partitions of 1TB each (zfs create -s -V 1tb idrive/d1). Access to the shares with an iscsi initiator was successful, all was smooth, until the reboot. Upon reboot, the console reports the following errors. WARNING:

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
