Steps
1.
Verify that your system configuration is
Multi-Path HA
or
Multi-Path
(single-controller-
dual-path):
sysconfig
For multipath HA configurations operating in 7-Mode, you can run the command from either
controller. For clustered systems, you run this command from the nodeshell.
It might take up to a minute for the system to complete discovery.
The configuration is listed in the
System Storage Configuration
field.
Note: For FAS22xx and FAS25xx systems with external storage, the output is displayed as
Mixed-Path HA
for an HA pair, and
Mixed-Path
for a single-controller configuration.
This is because the internal storage is cabled differently than the external storage. For an
HA pair, the internal storage is cabled as single-path HA and the external storage is cabled
as multipath HA. For a single-controller configuration, the internal storage is cabled as
single-path and the external storage is cabled as dual-path (multipath).
Attention: If your non FAS22xx or FAS25xx
system is shown as something other than
Multi-
Path HA
or
Multi-Path
, you cannot continue
with this procedure. Your system must meet the
prerequisites stated in the "Before you begin"
section of this procedure.
2.
Verify that no aggregates are on the disk drives in the disk shelves you are removing, by
completing the applicable substeps:
If your system is operating in... Then...
7-Mode
a. Enter the following command:
aggr status -r
If you have traditional volumes, you enter the
vol status -r
command.
For multipath HA configurations, you can enter the command from the
console of either controller.
b. Check the output
SHELF
column to verify that the disk shelves from which
you have removed aggregates do not appear.
Clustered Data ONTAP
a. Enter the following command from the clustershell:
storage disk show -shelf shelf_number -container-type !
spare
For multipath HA configurations, you can enter the command from the
console of either controller.
b. Check the output to verify that all the disk drives in the disk shelves you are
removing are spares or failed.
If all disk drives are spares, the output message is
There are no
entries matching your query
. If any disk drives are failed, output
contains a line item for each failed disk drive and shows the disk drive as
broken
.
Attention: If any disk drives in the disk shelves you
are removing are anything other than spares or
failed, you cannot continue with this procedure.
