I have 2 drives in RAID 1 configuration, as Ubuntu 16 boot drives. One of the drives failed and recovered by itself and I now have the following output:
root@server:/home/admin/megacli/Linux# megasasctl
a0 PERC H310 Adapter encl:1 ldrv:1 batt:FAULT, module missing, pack missing, charge failed
a0d0 931GiB RAID 1 1x2 DEGRADED
unconfigured: a0e*s0
a0e*s0 931GiB ready
a0e*s1 931GiB a0d0 online
root@server:/home/admin/megacli/Linux# megacli -pdgetmissing -aALL
Adapter 0 - Missing Physical drives
No. Array Row Size Expected
0 0 0 953344 MB
Exit Code: 0x00
What megacli commands do I need to enter to get the a0e*s0 back online like the other drive?
