Hi Eugene I guess you read my post on zfs-discuss, regarding Tano's similar problem: http://mail.opensolaris.org/pipermail/zfs-discuss/2008-October/052137.html
It would be interesting to get an Ethernet capture file from you, for the VMotion period. Could you make it available via http, and then I could take a look & see if it looks like the same pattern. You Ethernet link looks fast! For interest, what cards & switches are you using? Maybe you could run 'prstat' and 'vmstat' during the problem period to try & identify if anything is becoming stressed out on the Solaris server during the VMotion. Ok, how about this for an idea: The iscsitgtd on my snv_97 worked fine when we recently tested VMotion. How about if you replace the binary executable on your system (I think it was snv_99) with the one from mine. I think/hope it stands a good chance of running. I assume your 64-bit, so I have made it available here: http://www.nwsmith.net/solaris/iscsitgtd (Of course, keep a backup of the original file, and do a 'svcadm stop iscsitgt' before replacing the file, then a 'svcadm start iscsitgt') For reference, here's some information from my system: # uname -a SunOS sol-nv 5.11 snv_97 i86pc i386 i86pc # isainfo -kv 64-bit amd64 kernel modules # find /usr/sbin -name iscsitgtd | xargs ls -l -r-xr-xr-x 1 root bin 488616 Aug 23 21:54 /usr/sbin/amd64/iscsitgtd -r-xr-xr-x 1 root bin 397924 Aug 23 21:54 /usr/sbin/i86/iscsitgtd -r-xr-xr-x 96 root bin 8148 Aug 23 21:12 /usr/sbin/iscsitgtd # find /usr/sbin -name iscsitgtd | xargs file /usr/sbin/amd64/iscsitgtd: ELF 64-bit LSB executable AMD64 Version 1 [SSE2 SSE FXSR CMOV FPU], dynamically linked, not stripped, no debugging information available /usr/sbin/i86/iscsitgtd: ELF 32-bit LSB executable 80386 Version 1 [FPU], dynamically linked, not stripped, no debugging information available /usr/sbin/iscsitgtd: ELF 32-bit LSB executable 80386 Version 1 [FPU], dynamically linked, not stripped, no debugging information available # find /usr/sbin -name iscsitgtd | xargs digest -a md5 -v md5 (/usr/sbin/amd64/iscsitgtd) = c27b29c72527bd5eff51be11bffb3082 md5 (/usr/sbin/i86/iscsitgtd) = c0eea5fa3e0662186c2f52e6680b577a md5 (/usr/sbin/iscsitgtd) = e72d609561e281e7d723525e92b86726 Ok, let's see if that work, and what, if any, difference it makes.
