I have a fas2554 - twin controller
in this device i have 2x2tb sata drives
and 4 x ssd drives for cache
these drive as above are spare
when i try to create a storage pool i get the message:
(not enough disks)
so online help directs me to create via cli:
storage pool create -storage-pool SP1 -disk-list 1.0.1,1.0.2,1.0.3,1.0.0
Error: command failed: Disk "1.0.1" cannot be shared. Reason: Disk is not
can any body direct me on how to setup the ssd cache on this device?

With Storage Pools, we need a physical spare... with 4x SSD, create the pool with 3 disks. Then you have 1 spare. Then modify the aggregate with hdd "aggr modify -hybrid-enabled true" then "aggr add-disks -storage-pool spname -allocation-units xx" to assign allocation units... 2 per node available by default in the HA-Pair (4 allocation units total).

but: if i try with three disks:
NH-SAN-Netapp::> storage pool create -storage-pool SP1 -disk-list 1.0.2,1.0.3,1.0.0
Error: command failed: Disk "1.0.2" cannot be shared. Reason: Disk is not
swaped disk order just in case
NH-SAN-Netapp::> storage pool create -storage-pool SP1 -disk-list 1.0.3,1.0.0,1.0.1
Error: command failed: Disk "1.0.3" cannot be shared. Reason: Disk is not
and with two disks
NH-SAN-Netapp::> storage pool create -storage-pool SP1 -disk-list 1.0.3,1.0.0
Error: command failed: disk-list contains an invalid number of disks. The
number of disks in a storage pool must be from 3 to 28.

Any chance those disks are already partitioned (probably, during installation)?
You cannot use SSDs that have been partitioned for root-data partitioning in a storage pool

so, as this is a blocker to putting data on the system (i want it working correctly before it goes into production) i decided to zero the disk and setup a fresh
went thru the setup again and its the same as before!
as in setup, i selected the option as below, so no the disk should not be partioned
