[OmniOS-discuss] 2x acctual disk quantity

[Hafiz Rafibeyli]

Saso thank you for your fast reply,

its ok about two ports(sas dp)I know it,

but my question is about ,which disk adresses to use in my zfs mirror or zfs raid config?

in my case:

c4t500000E1168BB382d0          
c4t500000E11693F232d0          
c4t500000E11696D5A2d0          
c4t500000E116974FB2d0          

OR

c6t500000E1168BB383d0          
c6t500000E11693F233d0          
c6t500000E11696D5A3d0          
c6t500000E116974FB3d0          


If I understand right,when use first adresses I will use  1st controller only,and when use second addresses  2nd controller only?

regards

Hafiz

Hey Hafiz,

What you're seeing are the two ports of the disks. Using "mpathadm list
lu" you should be able to determine which SAS addresses correspond to
which disks. You can also use something like diskmap.py from
https://github.com/swacquie/DiskMap (it requires the sas2ircu utility
from LSI).

Cheers,
