[CentOS] LSI MegaRAID experience...

Hey,

anyone using an LSI MegaRAID experienced "disappearing drives"...?
We installed 6 new C6 servers, each with a Supermicro SMC2108 (LSI MegaRAID)
controllers and 3 PX-128M5Pro SSDs ( RAID1 + hostswap).
2 weeks (and almost no activity on it, since not in production, apart from
installation) later, megacli sees (based on the slot numbers):
- on one server: only the 2nd disk of the RAID + the ex-hotswap brought online.
NO sign of the first disk, no error message, it just "disapeared"...
- on another server: apparently lost 1 of the 2 RAID1 disks and then the second
disk of the RAID1...? Now I can only see the spare brought online, so lonely...
Is it "normal" for megacli to "hide" failed disks?
Controller's firmware is the latest.
SSDs's firmware are not... will try to flash them.
BTW, any tips to flash them through the RAID controller instead of having to
remove them all and connect them to a SATA controller...?
This is a bit scary...

Thx,
JD
