You can learn anything you need about your disk with the following commands:
I do not know what you are referring to by "serial number" but I do not doubt whatever it is you might find it using:
Some of them requires superuser privileges.

System: PowerPC_POWER6

I was told that a disk (hdisk 10) is bad. How can I find "the serial # of the storage enclosure" from command line? How do I find which disk is on which enclosure?
Thank you in advance! :)

Hi Experts,
In a particular dir, I have many files *AJAY*.
How can I get total size of all such files.
I tried du -hs *AJAY* but it gave me individual size of all files.
All I require is summation of all.
Thanks,

sysinfo
SYSINFO(2) Linux Programmer's Manual SYSINFO(2)NAME
sysinfo - return system information
SYNOPSIS
#include <sys/sysinfo.h>
int sysinfo(struct sysinfo *info);
DESCRIPTION
sysinfo() returns certain statistics on memory and swap usage, as well as the load average.
Until Linux 2.3.16, sysinfo() returned information in the following structure:
struct sysinfo {
long uptime; /* Seconds since boot */
unsigned long loads[3]; /* 1, 5, and 15 minute load averages */
unsigned long totalram; /* Total usable main memory size */
unsigned long freeram; /* Available memory size */
unsigned long sharedram; /* Amount of shared memory */
unsigned long bufferram; /* Memory used by buffers */
unsigned long totalswap; /* Total swap space size */
unsigned long freeswap; /* Swap space still available */
unsigned short procs; /* Number of current processes */
char _f[22]; /* Pads structure to 64 bytes */
};
In the above structure, the sizes of the memory and swap fields are given in bytes.
Since Linux 2.3.23 (i386) and Linux 2.3.48 (all architectures) the structure is:
struct sysinfo {
long uptime; /* Seconds since boot */
unsigned long loads[3]; /* 1, 5, and 15 minute load averages */
unsigned long totalram; /* Total usable main memory size */
unsigned long freeram; /* Available memory size */
unsigned long sharedram; /* Amount of shared memory */
unsigned long bufferram; /* Memory used by buffers */
unsigned long totalswap; /* Total swap space size */
unsigned long freeswap; /* Swap space still available */
unsigned short procs; /* Number of current processes */
unsigned long totalhigh; /* Total high memory size */
unsigned long freehigh; /* Available high memory size */
unsigned int mem_unit; /* Memory unit size in bytes */
char _f[20-2*sizeof(long)-sizeof(int)];
/* Padding to 64 bytes */
};
In the above structure, sizes of the memory and swap fields are given as multiples of mem_unit bytes.
RETURN VALUE
On success, sysinfo() returns zero. On error, -1 is returned, and errno is set to indicate the cause of the error.
ERRORS
EFAULT info is not a valid address.
VERSIONS
sysinfo() first appeared in Linux 0.98.pl6.
CONFORMING TO
This function is Linux-specific, and should not be used in programs intended to be portable.
NOTES
All of the information provided by this system call is also available via /proc/meminfo and /proc/loadavg.
