Symptoms
A Sun StorEdge[TM] T3/T3+ volume initialization, using the command "vol init", fails with the error message:

 ERROR (200015) VN_RAIDERR: RAID error

There is no other indication of failure. A volume can be created or added without any problem.

Example:

   t3h:/:<20>vol add vol1 data u1d01-04 raid 5 standby u1d09

   t3h:/:<1>vol list
volume            capacity raid data       standby
vol1             67.445 GB    1 u1d01-04     u1d09

   t3h:/:<21>vol init vol1 data
WARNING - Volume data will be initialized to zero.
WARNING - Volume initialization can take a significant amount of time.

ERROR (200015) VN_RAIDERR: RAID error

Resolution
Root Cause
At least one of the T3/T3+ drives is not in a usable state. The operational state is not showing STATUS "ready", and STATE "enabled".

Below is an example of an abnormal DISK (u1d04):

       STATUS   STATE
-------  ----------
offline  enabled
fault    disabled

 DISK    STATUS   STATE       ROLE        PORT1      PORT2      TEMP  VOLUME
------  -------  ----------  ----------  ---------  ---------  ----  ------
u1d01   ready    enabled     data disk   ready      ready      40    v1-r5
u1d02   ready    enabled     data disk   ready      ready      38    v1-r5
u1d03   ready    enabled     data disk   ready      ready      40    v1-r5
u1d04   offline  enabled

 DISK    STATUS   STATE       ROLE        PORT1      PORT2      TEMP  VOLUME
------  -------  ----------  ----------  ---------  ---------  ----  ------
u1d01   ready    enabled     data disk   ready      ready      40    v1-r5
u1d02   ready    enabled     data disk   ready      ready      38    v1-r5
u1d03   ready    enabled     data disk   ready      ready      40    v1-r5
u1d04   fault    disabled

Resolution Steps:

Confirm if the questionable drive is truely defective.
- Pull out and reseat the questionable drive.
- If reseating the drive does NOT help, attempt to power-cycle the array, AFTER ensuring that ALL the volumes in the array are NOT used.
Once the questionable drive is confirmed to be defective, proceed with drive replacement.

Relief/Workaround
In the following example, a new volume "v1-r5" is created with only 3 drives instead of the original 4, i.e. drives "u1d01-03" instead of "u1d01-04".

    t3h:/:<24>vol add v1-r5 data u1d01-03 raid 5 standby u1d09

    t3h:/:<25>vol init v1-r5 data
WARNING - Volume data will be initialized to zero.
WARNING - Volume initialization can take a significant amount of time.
Continue ? [N]: y
Volume initialization in progress...

    t3h:/:<26>vol list
volume            capacity raid data       standby
v1-r5            67.445 GB    5 u1d01-03     u1d09
