RAID rebuild will stop after 1-2% and stuck on "Ready for Rebuild"

Hello,

We have an DL180 G5 with Smart Array P400, and with 2 RAID5 arrays on it.

# hpacucli controller slot=6 ld all show

Smart Array P400 in Slot 6

array A

logicaldrive 1 (3.4 TB, RAID 5, Ready for Rebuild)

array B

logicaldrive 2 (199 MB, RAID 5, OK)
logicaldrive 3 (9.1 TB, RAID 5, OK)

we had a failed drive which we replace and that initiate the rebuild for array B,
but now we have array A stuck on "Ready for Rebuild" for few days now.

If i restart the machine, the rebuild process will start again, but will stop after 1-2% of progress.

All the PhysicalDrivers are ok

# hpacucli ctrl slot=6 pd all show status
