1) Can someone tell me what command I can use to find out the system processor speed.
2) Can someone tell me what command I can use to find out what's the hard drive size of my unix box.
3) Can... (1 Reply)
Hi,
Can someone answer to my question.I' totally new to Unix.

Hi
I have 2 75GB SCSI hard drives and 2 250GB SATA hard drives which are using RAID Level 1 respectively. I wana have both FTP and Apache installed on them as services. I'm wondering what's the best partitioning schem? I wana use FC3 as my OS, so, I thought I can use the 75GB hard drive as the /... (0 Replies)
Good day,
I have an rs/6000 server, model 7044-270. I bought a 2nd hard drive for it but im not sure its the right one. (fru:H13060) As you surely know, the 7044-270 hard drives are put in some sort of tray/carrier. There is a cable that will interface the HDD with the tray/carrier so the... (0 Replies)
Hi,
I just set up a raid Z array in solaris xpress and I notice that the drives feel pretty damn hot. I use speedfan to monitor the temperatures of the hard drives in XP. Is there a similar program for solrais? I assume there would be since the drives all have temp sensors in them, but I... (2 Replies)
Hi, I just downloaded and installed Ubuntu yesterday. It's the first time I have used it, so bear with me. I think I figured out how to get my sound drivers to work (X-Fi)... I had downloaded some OSS drivers, bout to go test them.
But what I really want to know is... I have 2 hard drive,... (2 Replies)

SD(4) Linux Programmer's Manual SD(4)NAME
sd - Driver for SCSI Disk Drives
SYNOPSIS
#include <linux/hdreg.h> /* for HDIO_GETGEO */ #include <linux/fs.h> /* for BLKGETSIZE and BLKRRPART */
CONFIG
The block device name has the following form: sdlp, where l is a letter denoting the physical drive, and p is a number denoting the parti-
tion on that physical drive. Often, the partition number, p, will be left off when the device corresponds to the whole drive.
SCSI disks have a major device number of 8, and a minor device number of the form (16 * drive_number) + partition_number, where drive_num-
ber is the number of the physical drive in order of detection, and partition_number is as follows:
partition 0 is the whole drive
partitions 1-4 are the DOS "primary" partitions
partitions 5-8 are the DOS "extended" (or "logical") partitions
For example, /dev/sda will have major 8, minor 0, and will refer to all of the first SCSI drive in the system; and /dev/sdb3 will have
major 8, minor 19, and will refer to the third DOS "primary" partition on the second SCSI drive in the system.
At this time, only block devices are provided. Raw devices have not yet been implemented.
DESCRIPTION
The following ioctls are provided:
HDIO_GETGEO
Returns the BIOS disk parameters in the following structure:
struct hd_geometry {
unsigned char heads;
unsigned char sectors;
unsigned short cylinders;
unsigned long start;
};
A pointer to this structure is passed as the ioctl(2) parameter.
The information returned in the parameter is the disk geometry of the drive as understood by DOS! This geometry is not the physical
geometry of the drive. It is used when constructing the drive's partition table, however, and is needed for convenient operation of
fdisk(1), efdisk(1), and lilo(1). If the geometry information is not available, zero will be returned for all of the parameters.
BLKGETSIZE
Returns the device size in sectors. The ioctl(2) parameter should be a pointer to a long.
BLKRRPART
Forces a re-read of the SCSI disk partition tables. No parameter is needed.
The scsi(4) ioctls are also supported. If the ioctl(2) parameter is required, and it is NULL, then ioctl() will return -EINVAL.
FILES
/dev/sd[a-h]: the whole device
/dev/sd[a-h][0-8]: individual block partitions
