megaraid driver only seeing 2 of 3 logical dirve.

megaraid driver only seeing 2 of 3 logical dirve.

[Byron Albert]

I just added an ami megaraid card to a machine. I configured the 6  9gb
drives to look like 3 18gb drives and then booted. Linux only saw 2 of
the 3 drive.  I think got the latest kernel and compiled and rebooted
and the same below is the relevant dmesg info.  It says it detected 3
logical drives but the driver only uses two of them.

I really need this other drive so any help would be appreciated.

The driver you are using seems to be not what we had released ( as I could
make out from the dmesg ) . Which distribution/kernel are you using. I
recommend you to get 1.17c, which is the latest driver. I will mail it
separately to you since sending attachments on this list is probably not a
good idea

1.17a is the last release that went into the mainstream, then updated to
1.17a-ac to fix a tiny problem with HP controllers (the fix I then sent back
on upstream)


If 1.17c is recommended you might want to send Linus and I an update
