BIA index error, after upgrading to REV 52

HI all ,

Recently we upgraded to Rev 52. In the BIA monitor we got red falg, saying, Check for activity on master index server. In the details it shows list of some cubes. for these cubes, we are unable to index. It shows the fallowing message.

@5C@ Creation of index 'GRQ_BIC:SETVDTIND' terminated. Error text:

@5C@ The index is temporary not available;index=grq_bic

@5C@ :setvdtind 2972

@5C@ Creation of BIA index for InfoCube 'ETVC00001' terminated during activation

We restarted all the server blades also.

Could any one suggest to how to overcome this issue?

Regards,

Balaji.
