Restore t1/t2
Date: 2011/10

On 2011/09/19, both t1 and t2 harddisk failed at the summit.
T1hilo was rebuilt with new motherboard, cpu, etc. And a complete reinstall of the OS (centos 4.9)
Then t1/t2 was restore using the t1hilo image.

0. BIOS notes from previous installation:

   setup bios to trigger warning on CPU over temperature and CPU fan error.
   setup boot device order: dvd, harddisk

1. Prep harddisk

New partition scheme is:
   /dev/hdb1 - /        20 GB  - restored from t1hilo backup.
   /dev/hdb2 - /r2      20 GB  - exta boot partition.
   /dev/hdb3 - /aux     20 GB  - aux parition (/home, /catalogs).
   /dev/hdb4 - /aux1    rest   - unused.

Format the drives:
   mkfs.ext3 -v -m 3 /dev/hdb1  (do all the partitions)

2. Restore 

   boot dvd in 'linux rescue' mode.

   mount 128.171.110.145:/irtf.backup /irtf.backup

   mount /dev/hdb1  /b1
   cd /b1
   restore rvf /irtf.backup/HOST/YYMMDD.root.zdump

   mount /dev/hdb3  /b3
   cd /b1
   restore rvf /irtf.backup/HOST/YYMMDD.aux.zdump

2. setup grup 

   /b1/sbin/grub
   > root (hd0,0)                  note: hdb1 is hd1,0
   > find /boot/grub/stage1
   > setup (hd0)                   This command installs GRUB on MBR.

3. configure ethernet

   /etc/hosts
