Hi Folks,
I've been giving CTL a try and thought things were going well.
I installed a QLogic 2532 card in a ZFS server and a second in
a rh62 linux system. Src is current as this afternoon - r255479.
isp0: <Qlogic ISP 2432 PCI FC-AL Adapter> port 0x8000-0x80ff mem 0xfbdf0000-0xfbdf3fff irq 64 at device 0.0 on pci33
isp1: <Qlogic ISP 2432 PCI FC-AL Adapter> port 0x8400-0x84ff mem 0xfbde0000-0xfbde3fff irq 68 at device 0.1 on pci33
I create a lun via:
ctladm create -b block -o file=/dev/zvol/pool0/testvol -S serialnum-fc -d testvol
ctladm realsync off
ctladm port -o on -t fc
ctladm port -l
ctladm devlist -v
LUN created successfully

I can run commands against the lun from the linux side with
no problems. For instance:
# sg_inq /dev/sdc
standard INQUIRY:

# sg_readcap /dev/sdc
Read Capacity results:
Last logical block address=209715199 (0xc7fffff), Number of blocks=209715200
Logical block length=512 bytes
Hence:
Device size: 107374182400 bytes, 102400.0 MiB, 107.37 GB
However, when I try to partition the drive and format it, the ZFS server
panics with the following:

I can replicate this on demand at this point so please let me
know if there is any information I can provide.
Any ideas where to go from here?
Thanks,
John
