Red Hat Bugzilla – Bug 8230
Raid controller ok in 6.0 then after upgrade partions lost.
Last modified: 2015-01-07 18:40:26 EST
Here is the intro:
Dell 4100/200 with an OEM megaraid 1200 controller - 4 drives (4.2Gb)
For the sake of storage - I have configured them Raid 0.
For some time the system has run RH 6.0 aok with the above drive config.
Then I ugpgrade to RH 6.1 and all I can see is the first drive.
Yes - I have gone to AMI's web site and loaded their driver v1.04 -
followed their instructions. I have upgraded the Bios to U.81 (from Dell's
ftp server - not AMI's) and still no joy.....
Question: If I could use the raid array with RH 6.0 aok, what "Enhancement"
has caused RH 6.1 to drop the last three drives...??
Apart from that great product - and I do plan to put 15 years tec support
behind this product...
assign to installer
In the readme file for the megaraid driver, it states that you should check to
make sure that "probe all LUN's" when configuring your kernel. Might want to
check that, I don't know how it comes out of the box. Also they are up to
version 1.07 now, I highly recommend the upgrade since everything short of 1.05
hangs under heavy IO.
This is fixed in the latest version of the installer (Red Hat Linux 6.2)
