Title: SATA drive question
Post by: OzMoosis on February 17, 2007, 03:43:49 PM

Hi,

I'm trying to install SME7.1 on a new server. Hardware is Intel S3000AHV board, with P4 CPU, 1 GB of Kingston RAM and a pair of Samsung HD080HJ SATA II disks for RAID 1. Intel says the board is compatible with Redhat Enterprise 4, so should be OK for SME. (?)

Strange things are happening, though:

- SME takes about 30 minutes to install which is far longer than I'm used to.
- After installation SME identifies the disks as hda and hdb, and not sda/sdb as I thought it would.
-  RAID 1 disk-mirroring proceeds at a speed of about 1600 kB/s. Total time is calculated to be more than 15 hours!! But server hangs after 1 hour.

Does anybody have idea what could be wrong, or have experience with these hardware components?? I've tried settings jumpers on the disks to limit them to 1,5 GB/s, that only made things worse.....

Thanks,

Oz

General advice, as I don't know the motherboard:

- Check that you don't have some funky SATA->PATA mapping happening in your BIOS. SATA drives should appear as /dev/sd?.
- Disable the onboard RAID controller, if the board has one.
- If you needed to load a driver disk, do it without.
- If it doesn't work without, and you can't disable any onboard RAID controllers, take it back.

Hi,

As a collegue of Oz i can answer your sugestions.
There's no SATA->PATA mapping going on, as far as I can see.
Raid present but disabled.
Generic SATA-driver works for single satadisk.

One idea rises from your suggestions.
let's use the driverdisk if there is any!

There is a bios-update but i don't expect much of this.

Just in case other users are having similar issues: we have found what the problem was: we had installed SME 7.1 from a USB cd-rom drive. Apparently this confused SME into not recognizing the HD's properly. After reinstalling from IDE cd-rom, our harddrives were seen as sda and sdb, and (mirroring)speed was back to normal (45936 K/sec),
