NetApp and Solaris

Solaris NetApp Just some unsorted lines...

Timeout settings in Solaris

Settings for MPxIO over FC:

/kernel/drv/ssd.conf

ssd-config-list="NETAPP  LUN","netapp-ssd-config";
netapp-ssd-config=1,0x9007,64,300,30,0,0,0,0,0,0,0,0,0,30,0,0,8,0,0;

/kernel/drv/sd.conf

sd-config-list=
"NETAPP  LUN","physical-block-size:4096";

Alignment and ZFS

First read ZFS zpools create misaligned I/O in Solaris 11 and Solaris 10 Update 8 and later (407376).

If you have 4k as block size in your storage use ashift=12.

ashift=12? Why 12?

# echo "2^12" | bc -l
4096

OK... 4k... I see.

Create ZPools on NetApp LUNs with this syntax

# zpool create -o ashift=12 <mypool> mirror <vdev1> <vdev2>
