Symptoms



If an SSD drive reports in NONE state it would mean that the drive has not been given purpose (either storage or L3 cache):

- To remedy the drive will need to be given a purpose (storage or L3 cache, as required) 

# isi devices drive purpose 1 --purpose=storage
You are about to purpose drive bay1, on node lnn 152. Are you sure? (yes/[no]): yes

- The drive then goes into PREPARING and, eventually, HEALTHY state:

One way to infer whether an SSD drive should be storage or L3 cache is to view the details for its partner SSD drive:

Cabbage-2# isi devices drive view 1
                  Lnn: 2
             Location: Bay  1
                 Lnum: 43
               Device: /dev/da1
               Baynum: 1
               Handle: 327
               Serial: 2LVV39PA
                Model: HGST HUSMM8040ASS200
                 Tech: SAS
                Media: SSD
               Blocks: 781422768
 Logical Block Length: 512
Physical Block Length: 4096
                  WWN: 5000CCA02B2F7857
                State: L3
              Purpose: L3
  Purpose Description: A drive used for L3 caching rather than storage
              Present: Yes

Cause

This is a very rare scenario that occurs when adding new drives, caused by conflict between mount_efs and isi_drive_d that causes drive purposing to not assign a purpose to the SSD drive.

Resolution

- To remedy the drive will need to be given a purpose (storage or L3 cache, as required) 

# isi devices drive purpose 1 --purpose=storage
You are about to purpose drive bay1, on node lnn 152. Are you sure? (yes/[no]): yes

- The drive then goes into PREPARING and, eventually, HEALTHY state:
