We are planning an array expansion on a Smart Array 6400 controller. Array is 0+1 with hot spare. My question is what will happen if during the expansion process battery fails? The expansion process should pause, because the write cache needed for the expansion process is disabled when there is a broken battery.
Is it possible in that situation to power off the server and replace the battery on the controller? Is there any risk of data loss? Will the array expansion continue after the battery replacement?
Thank you for your answers.
Solved! Go to Solution.

Re: Battery failure during array expansion
Hi,
we have a Proliant DL380, using Array controller P400 with battery backup.
attached to the controller:
2 disk 72GB using raid 1, Ubuntu NOS Array 1
3 disk 146GB using RAID 5 for data. ARRAY 2
Array 1 and Array 2, use one partition or logical drive.
Array 2 is full, 95% of disk usage.
We upgrade the server with additional Memory RAM, and 3 additional disk SAS - 146GB - 10k.
ACU is not available as application for UBuntu, so follow this steps:
1. Turn off the server
2. Boot using SmartStart 8.15 ver.
3. Choose Maintenance Server Option
4. Choose ACU
5. The new disks installed appear linked to the RAID controller
6. We choose the expand array option on Array 2.
After that and a confirmation screen, we AGREE, and a screen showing a RAID expanding appear
The problem is with the proccess, this screen is not showing a progress bar, and we don't know if the process is complete.
Can we restart the server without data loss ?, remember this server is using Ubuntu and Ebox so is used as a PDC.
Help, may I restart the server ?, I need it on the air urgent.
Thanks for your help.
Medardo
