OnCommand unified manager 5.1 cDOT volume comments available

[scheckel]

Hi,

does OnCommand unified manager capture volume comments from cDOT

Here is an example

derotnpc0001::> vol show -vserver derotvs00001 -volume testvol1 -fields comment

  (volume show)

vserver      volume   comment

------------ -------- -------------------------------------

derotvs00001 testvol1 THIS_COMMENT_NEEDS_TO_BE_IN_OnCommand

So with this comments we want to use WFA for making sure, that indirect path is prevented. There would be plenty of use cases.

Best wishes,

Markus.

Hi Markus,

     I doubt that this comment is captured in OCUM. To the best of my knowledge its not. But alternatively you can use the comment field of OCUM to do something similar.

Hi Adai,

we want to manage this data in the cluster and outside. As we want do use WFA it will be much easier to maintain only one point.

The idea as we create a new volume we put a comment about which LIF is used to mount that volume. This helpfull information to keep the LIF and the volumes on the same nodes. Would it be possibel to implement this in ONUM or will it be in V6?

Best wishes,

Markus.

Hi Markus,

  Thanks for the use case. This can be easily done in OCUM 5.1 using custom comment field. Checkout the CLI dfm comment field create and set.

Also I just found out that this info is not there in v6 as well

Hi Adai,

thanks for taking your time.

Would be great if UM will get all atributes from a volume. Is there still a way to get a RFA for the future?

Best wishes,

Markus.

Hi Adai, 

Here is another use case why it's very important to have the comment field from a volume in the OCUM. 

Many customers have with cDOT a volume naming policy without any useful human readable strings.

Like: 

vol_cifs_15

vol_cifs_51

vol_cifs_251 

and so on ... 

So the storage admin will take the comment field for a human readable description for each volume.

With any reports for the management, the storage admin has to match the volume name with the comment field.

If we have no comment field, based on the volume comment field on the storage,

in the OCUM, there will be an Excel list and a lot of manual work... 

No Manager wants do this by him self or wants to see in the report that a volume name like vol_cifs_256 increase 200%.

They want see that the volume for the Developers 200% increase.  

Best Regards,

Rene
