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> /scsi_vhci/ssd at g60a98000433469764e4a413571444b63 2. c4t60A98000433469764E4A41357149432Fd0 <NETAPP-LUN-0.2-50.00GB> /scsi_vhci/ssd at g60a9...

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 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.

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 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

Is it possible to use DTrace to display the number of arguments and their types for userland or kernel functions that are not explicitly instrumented or documented by their authors? We''re talking about functions provided by Veritas VxVM/VxFS and the like, and for example, we might want to try tracing I/Os from App => VxFS => VxVM => ssd driver to see where I/Os get aggregated or

Since this system has been up, over the past 2.5 years, this has never happened before. When we got the thing glued back together, it immediately started resilvering from the beginning, and reported about 1.9 million data errors. Th...
