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.
What ashift do I have?
# zdb | egrep 'ashift| name'
name: 'apache_pool'
ashift: 9
name: 'mysql_pool'
ashift: 9
...
Create ZPools on NetApp LUNs with this syntax
# zpool create -o ashift=12 <mypool> mirror <vdev1> <vdev2>
