Re[2]: Urgent SCSI I/O Error

[Manohar Pradhan <mpml@isp.primuseurope.com>]

Hi All,

If the Hard Drive is died, means I will need to replace. I have backup
for the Data in that /www partition.

Means when I replace new HDD, I will have to partition/format using
fdisk /sda ?

>From my partition info,

/dev/sdb6               917072    732972    137516  84% /
/dev/sda1                18820      5811     12037  33% /boot
/dev/sda6              2218336    462492   1643156  22% /www
/dev/sda5              5297560    418936   4609520   8% /home
/dev/sda7              1210440    711516    437436  62% /software
/dev/sdb1              5550188     50896   5217356   1% /usr
/dev/sdb5              2016016     28572   1885032   1% /var


My problematic HDD is /sda so if I replace this HDD, how can I boot as
boot images are in /sda1 /boot partition. How can I copy this boot
images to somewhere and make it work and what will be the process?

I know if I reboot and replace the HDD, it will give problem while
booting, any Idea to struggle with this?

Thanks a lot for all your help.

Regards
Manohar
