Andres,

Go ahead and flash the perc firmware to the latest, v.516A from
http://support.dell.com/support/downloads/format.aspx?c=us&cs=555&l=en&s
=biz&SystemID=PWE_PNT_2800&os=LE30&osl=en&deviceid=6395&devlib=35&catego
ry=0&releaseid=R94664

Might also look at using the DKMS megaraid driver so that you stay with
what seems the more stable megaraid-2.10.7.
http://support.dell.com/support/downloads/format.aspx?c=us&cs=555&l=en&s
=biz&SystemID=PWE_PNT_2800&os=LE30&osl=en&deviceid=6395&devlib=35&catego
ry=0&releaseid=R79751  Once you've got DKMS installed, you can do kernel
updates without having to manually recompile the driver every time.

Thanks,
Mike Davis

SD is requesting the Cache page from product data, since the controller
handles cache (vs a normal stand alone scsi drive) it interprets an
unsupport (there for no cache) result.

The controller will still do the do the caching as normal (and should
not cause a lockup).

Which megaraid version are you using ?

Hi,
 
I have a PE2800, has a 'PERC 4e/Di Standard FW 5130' RAID controller
card. After finishing the install and rebooting I get this:
 
sda: asking for cache data failed
sda: assuming drive cache: write through
       sda: sda1 sda2 sda3 sda4
 
My Linux server was frozen for unknown reason, any idea. ???. iam using
fedora3 ...

Hi Jonas,

Use the Dellmgr-5.32-0.i386.rpm in the perc-apps tgz.
http://support.dell.com/support/downloads/format.aspx?c=us&l=en&s=gen&Sy
stemID=PWE_PNT_P3C_2850&os=LE30&osl=en&deviceid=1370&devlib=35&category=
0&releaseid=R81687 

once installed just type 

dellmgr 

it will open a ncurses console. 

Go to objects/physical drive and highlight the suspect harddrive. Hit F2
and it will display any media errors or other errors (scsi bus errors)
for that drive.

Troy

Hello again! 

I found some more info: The internal controller is a PERC3/Di (internal
to PE2650). 

The extra controller says the following when booting:

Can anyone tell me how to access this controller (PERC3/DC) now to check
the defects lists of the disks?!?!

Subject:        Which disk in the mirror is having the problems? 

Hello! 

I got some SCSI errors in the messages log on a RedHat server: 

Jan 18 04:29:56 seprol03 kernel: SCSI disk error : host 1 channel 2 id 0
lun 0 return code = 25040005 Jan 18 04:29:56 seprol03 kernel:  I/O
error: dev 08:12, sector 16 Jan 18 04:29:56 seprol03 kernel: SCSI disk
error : host 1 channel 2 id 0 lun 0 return code = 25040005 Jan 18
04:29:56 seprol03 kernel:  I/O error: dev 08:18, sector 32780 

There are several other SCSI errors in the log but only devices 08:12
and 08:18 are shown, and 08:18 are many. 


So, does "dev 08:12" mean /dev/sda12 and "dev 08:18" mean /dev/sdb2? 

brw-rw----    1 root     disk       8,  12 Mar 19  2002 /dev/sda12 
brw-rw----    1 root     disk       8,  18 Mar 19  2002 /dev/sdb2 

/dev/sda12 is currently not used. /dev/sdb2 is used very much and it is
a raw device, and it is the processes using the raw device which is
having severe problems.


Both /dev/sda and /dev/sdb are mirrored devices (RAID 1). There are two
different RAID controllers in the machine. 

The RAID controller where /dev/sda is located is shown in the admin
interface "afacli". (I have opened the afa0 controller and run disk show
defects 0 and 1 and I get nothing in the "grown defects" list - is there
more to check for the disks?).

However I don't know how to access the other controller where /dev/sdb
is located. Is there another admin interface available? I think
something about LSI is said when the machine is booting.


Is there another way to check which disk in the mirror is causing the
problems? 

Regards
/bl?berg

Try looking at my Power Solutions article.  It has a good overview of
how that stuff works.

	Hi

	I read your post on
http://lists.us.dell.com/pipermail/linux-poweredge/2003-May/031439.html
<http://lists.us.dell.com/pipermail/linux-poweredge/2003-May/031439.html
>  and was wondering whether you could help me please.  I am also trying
to get a Dell snmp mib working with net-snmp BUT i'm not having any luck
so far.  I have downloaded the Dell_10892.txt mib file and stored it in
/usr/share/snmp/mibs on my linux box.  However when I run commands such
as "snmpwalk -c public -v2c -m ALL -OT <ip address of host in this case
it's localhost>" I don't see any information relating to the dell mib.

	I don't understand what I have to do once I have downloaded the
mib file, in addition to downloading the file do I have to run the mib2c
command? - if so how do I go abouts doing this?  Please could you offer
some advice or help in any way....i have done lots of reading around
this topic BUT so far haven't come up with anything.

	Thanks

	Anil
