Legacy Appliance D2DBackups Size Stuck at 200GB Following a Reimage

SUMMARY

Some legacy systems will incorrectly report D2D as 200GB following a reimage

ISSUE

The default value for D2DBackups is 200GB. Usually on a legacy system this can be directly modified from the storage menu. Under certain circumstances you may not be able to increase this value. If the system is licensed correctly, then this article will allow you to modify the limits for D2DBackups. 

RESOLUTION

Starting with 10.1.x the D2D storage can be auto-configured via Satori UI and the following steps: 
Under Configure > Appliances, down to the storage tab and select then edit the internal storage listing 
​
Set IR allotment to 1% (expecting shows as 0%) and then rerun smgr_display after saving the change.

smgr_display should now reflect correct D2D storage listing

If not follow below steps instead:

*** Caution:  For advanced users only. ***

*** May cause un-repairable damage! ***

The bp.nvp table holds several defaults for the system. One of these is the D2D backups limit. To verify it is incorrectly set, run the following query:

psql -U postgres bpdb -c "select * from bp.nvp where item_name='D2D'"

If the value is set to 200, or to a negative number, then this is the cause of the problem. Refer to the following table to determine the appropriate device D2D value (if the device is not in the list, retrieve the value from the license). 

Using the D2D value for your unit (7500 in this example) run the following command to update D2D in bp.nvp:

psql -U postgres bpdb -c "update bp.nvp set item_value='7500.000000' where item_name='D2D'"

Now, confirm that the new item value has been updated appropriately.
 

psql -U postgres bpdb -c "select * from bp.nvp where item_name='D2D'"
 nvp_type |   nvp_name    | item_name |  item_value
----------+---------------+-----------+--------------
 system   | configuration | D2D       | 7500.000000
(1 row)

After this, 'service httpd restart'

Then under Satori UI > Configure > Appliances, Storage > Internal, edit and adjust storage allotment for IR up then down and save to have UI adjust D2D configuration.

Once saved restart 'rcscript stop;rcscript start' services to affect smgr reservations.
