Hi Chaps,


I got an alert from CAM of Sun Storage Tek 6140 that batteries of both the controllers are going to expire in 41 days, I logged the call with oracle/sun and they consider this as CRU(customer replaceable unit) and send us the batteries to be replaced, hence it came on me as a DBA to replace the atteries of the both the controllers(A and B) of SunStorage Tek 6140.

under this circumstances, could you please advise me the following?

1. is it feasible to replace the batteries while systems(storage array,DB's and servers attached to it) are up and running? if I do so does this impact on performance? any risk?

2. on recieved batteries from Sun/Oracle it is not marked as this battery is for controller 'A' and the other for controller 'B', hence my question is that can we install any one of these batteries to controller A or controller B?

3. will there be a situation like CAM alerted as these going to expire in 41 days but may expire anytime before 41 days?


Thanks for your help in advance, I will really appreciate for the quick and effective responses.


regards
Abdul
