will list serial numbers for hard drives. This is the only way know of to tell if a disk was actually replaced with another disk. But you need to know the previous serial number. I do not know of any internal db that tracks previous device information like that. Don't you get some kind of invoice? If this is a coverage like we have, it is fully covered, so no cost involved.
You will see messages, but you cannot tell if the drive was actually replaced.
None of this applies to a SAN.

Hello guys,
I have got from a friend a hard disk which was used in the SCO OpenServer. He needs some data from it. I have no clue how to copy its content with Linux or Windows-I have tried few Linux distros but the result is always the same-the file system is not recognized so can't be mounted.... (4 Replies)
I am running FC-7 which I realize is an older distro. But my question would apply to any distro.

iostat
IOSTAT(8) BSD System Manager's Manual IOSTAT(8)NAME
iostat -- report I/O statistics
SYNOPSIS
iostat [-CdDITx] [-c count] [-M core] [-N system] [-w wait] [drives]
DESCRIPTION
iostat displays kernel I/O statistics on terminal, disk and CPU operations. By default, iostat displays one line of statistics averaged over
the machine's run time. The use of -c presents successive lines averaged over the wait period. The -I option causes iostat to print raw,
unaveraged values.
Only the last disk option specified (-d, -D, or -x) is used.
The options are as follows:
-c count Repeat the display count times. Unless the -I flag is in effect, the first display is for the time since a reboot and each sub-
sequent report is for the time period since the last display. If no wait interval is specified, the default is 1 second.
-C Show CPU statistics. This is enabled by default unless the -d, -D, -T, or -x flags are used.
-d Show disk statistics. This is the default. Displays kilobytes per transfer, number of transfers, and megabytes transferred.
Use of this flag disables display of CPU and tty statistics.
-D Show alternative disk statistics. Displays kilobytes transferred, number of transfers, and time spent in transfers. Use of this
flag disables the default display.
-I Show the running total values, rather than an average.
-M core Extract values associated with the name list from the specified core instead of the default ``/dev/mem''.
-N system Extract the name list from the specified system instead of the default ``/netbsd''.
-T Show tty statistics. This is enabled by default unless the -C, -d, or -D flags are used.
-w wait Pause wait seconds between each display. If no repeat count is specified, the default is infinity.
-x Show extended disk statistics. Each disk is displayed on a line of its own with all available statistics. This option overrides
all other display options, and all disks are displayed unless specific disks are provided as arguments. Additionally, separate
read and write statistics are displayed.
iostat displays its information in the following format:
tty
tin characters read from terminals
tout characters written to terminals
disks
Disk operations. The header of the field is the disk name and unit number. If more than four disk drives are configured in the sys-
tem, iostat displays only the first four drives. To force iostat to display specific drives, their names may be supplied on the com-
mand line.
KB/t Kilobytes transferred per disk transfer
t/s transfers per second
MB/s Megabytes transferred per second
The alternative display format, (selected with -D), presents the following values.
KB Kilobytes transferred
xfr Disk transfers
time Seconds spent in disk activity
cpu
us % of CPU time in user mode
ni % of CPU time in user mode running niced processes
sy % of CPU time in system mode
id % of CPU time in idle mode
FILES
/netbsd Default kernel namelist.
/dev/mem Default memory file.
