Tru 64 bit on HP AlphaServer ES45 creating problem Help Needed !!!
Dear All,
I am new on Tru 64 bit Unix platform. I have a database server "HP AlphaServer ES45" version p5.1 of Tru Ux 64 bit installed. I have 4 hard drives in this system (1,2,3,4). My 4th hard drive is damaged which contain Oracle database files including partitions on 4th drives (u01,u02,u03,u04). The Operating system is loading fine and these all drives are accessable and I am able to create new directories in theses drives but I am unable to mount these (u01,u02,u03,u04). When I am tyring to mount theses drive then "cannot read from the media due to corrup files" message arise.
Although this is our development server and the data in this drive 4 is not important for me. Kindly help me in this regard that how can format/delete/recreate these partitions and able to install database again on this machine.
If there is any chance of recovery for this drive also let me know.
I also need Administrator Guide for Tru 64 kindly provide me a link.
Thanks in advance.
Regards,
ntico

HD(4) Linux Programmer's Manual HD(4)
NAME
hd - MFM/IDE hard disk devices
DESCRIPTION
The hd* devices are block devices to access MFM/IDE hard disk drives in raw mode. The master drive on the primary IDE controller (major
device number 3) is hda; the slave drive is hdb. The master drive of the second controller (major device number 22) is hdc and the slave
hdd.
General IDE block device names have the form hdX, or hdXP, where X is a letter denoting the physical drive, and P is a number denoting the
partition on that physical drive. The first form, hdX, is used to address the whole drive. Partition numbers are assigned in the order
the partitions are discovered, and only nonempty, nonextended partitions get a number. However, partition numbers 1-4 are given to the
four partitions described in the MBR (the "primary" partitions), regardless of whether they are unused or extended. Thus, the first logi-
cal partition will be hdX5. Both DOS-type partitioning and BSD-disklabel partitioning are supported. You can have at most 63 partitions
on an IDE disk.
For example, /dev/hda refers to all of the first IDE drive in the system; and /dev/hdb3 refers to the third DOS "primary" partition on the
second one.
They are typically created by:
mknod -m 660 /dev/hda b 3 0
mknod -m 660 /dev/hda1 b 3 1
mknod -m 660 /dev/hda2 b 3 2
...
mknod -m 660 /dev/hda8 b 3 8
mknod -m 660 /dev/hdb b 3 64
mknod -m 660 /dev/hdb1 b 3 65
mknod -m 660 /dev/hdb2 b 3 66
...
mknod -m 660 /dev/hdb8 b 3 72
chown root:disk /dev/hd*
