Hi,
I want to change the ocean diag table. As a first step, I copied the existing diag table from `/g/data/access/access-cm2/input_O1/mom5_360x300/CMIP6_diagtable_as7904_20190814` to a local directory. I updated the path to the diag table in `/app/coupled/rose-suite.conf` and updated the storage flags in `suite.rc`.
When doing a test run (i.e. using the same diag table just from a different location) I get a `bad or missing value` error message. Does anyone have a suggestion what I’m doing wrong?
Thanks,
Wilma

Hi @wghuneke,
I’ve had a go repeating the same steps with the `u-cy339` suite.
Specifically changing:
#### `app/coupled/rose-app.conf`
```diff
[file:$OCN_RUNDIR/INPUT/diag_table]
-source=~access/access-cm2/input_O1/mom5_360x300/CMIP6_diagtable_as7904_20190814
+source=/g/data/lg87/sw6175/cm2-diagtable/CMIP6_diagtable_as7904_20190814
```
#### `suite.rc`
```diff
[[NCI]]
...
- -l storage = gdata/{{PROJECT}}+gdata/access+gdata/xp65+gdata/hr22+gdata/ki32
+ -l storage = gdata/{{PROJECT}}+gdata/access+gdata/xp65+gdata/hr22+gdata/ki32+gdata/lg87
```
This worked in a short 1 month run without crashing. Do these match the changes you made? Would you be able to copy the complete error message?
Thanks,
Spencer

Hi Spencer,
Thanks you for having a look into this.
I have the following storage flag in my `suite.rc`:
`-l storage = gdata/x77+scratch/x77+gdata/access+gdata/xp65+gdata/p66+gdata/hr22+gdata/ki32+gdata/lg87`
And my `app/coupled/rose-app.conf` looks like this:
`[file:$OCN_RUNDIR/INPUT/diag_table]`
`#source=~access/access-cm2/input_O1/mom5_360x300/CMIP6_diagtable_as7904_20190814`
`source=/g/data/x77/wgh581/inputs/access-cm2/mom5_360x300/CMIP6_diagtable_as7904_20190814`
This is the error message I get:

Argh, apologies. The path to the new location was wrong!

No worries, good to know that it is working!
