-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 i have two identical servers with identical hardware. the servers are sun fire x2250's with two 1 TB hard disks. on server #1, i installed ubuntu-server a couple weekends ago. in the BIOS i configured the disks to use AHCI mode. everything works great. i created two RAID-1 md devices. on md0 i formatted ext4 and put /boot. on md1 i put LVM with logical volumes for / and swap.
then, last weekend, i did the same thing (AFAIK) for server #2. only this time, after rebooting, the hard disks are no longer detected; the BIOS just hangs at "auto-detecting SATA PORT 0". if i change, in the BIOS, the disks back to IDE mode instead of AHCI, they get detected. isn't that strange? i tried to clear and re-setup the BIOS, didn't help. when i put the disks from server #2 into server #1, server #1 doesn't detect them either. i had another pair of disks from identical server #3 that i decided to try out. again, initially, they are detected fine in AHCI mode; i go and setup ubuntu-server on them similarly to the way i did on server #1; upon rebooting, the BIOS hangs detecting the disks. -----BEGIN PGP SIGNATURE----- iEYEAREIAAYFAkvvZBEACgkQXhfCJNu98qAUEwCfQjVJ34TO470RlYyTM4TPsWfu WyUAoJgfD+uv/9xogEWtQEit+uJVVbRc =iYP7 -----END PGP SIGNATURE----- -- ubuntu-server mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
