How are the disks attached ? a NAS, a SAN? what type?
But usually this sort of issues comes more from the OS side... Or SAN is flushing and syncing its cache but badly configured, not optimised to your usage (dont laugh I have seen cases with the best equipment...)
we have an unix system which has
load average normally about 20.
but while i am running a particular unix batch which performs heavy
operations on filesystem and database average load
reduces to 15.
how can we explain this situation?
while running that batch idle cpu time is about %60-65... (0 Replies)
Hello all, I have a question about load averages.
I've read the man pages for the uptime and w command for two or three different flavors of Unix (Red Hat, Tru64, Solaris). All of them agree that in the output of the 2 aforementioned commands, you are given the load average for the box, but... (3 Replies)
Hello, Here is the output of top command. My understanding here is,
the load average 0.03 in last 1 min, 0.02 is in last 5 min, 0.00 is in last 15 min.
By seeing this load average, When can we say that, the system load averge is too high?
When can we say that, load average is medium/low??... (8 Replies)
Hi,
i have installed solaris 10 on t-5120 sparc enterprise.
I am little surprised to see load average of 2 or around on this OS.
when checked with ps command following process is using highest CPU. looks like it is running for long time and does not want to stop, but I do not know... (5 Replies)
Hello AlL,..
I want from experts to help me as my load average is increased and i dont know where is the problem !!

Hi ,
I am using 48 CPU sunOS server at my work.
The application has facility to check the current load average before starting a new process to control the load.
Right now it is configured as 48. So it does mean that each CPU can take maximum one proces and no processe is waiting.

Hi,
I am getting a high load average, around 7, once an hour. It last for about 4 minutes and makes things fairly unusable for this time.
How do I find out what is using this. Looking at top the only thing running at the time is md5sum.
I have looked at the crontab and there is nothing... (10 Replies)

diskinfo
diskinfo(1M)diskinfo(1M)NAME
diskinfo - describe characteristics of a disk device
SYNOPSIS
character_devicefile
DESCRIPTION
The command determines whether the character special file named by character_devicefile is associated with a SCSI or floppy disk drive. If
so, summarizes the disk's characteristics.
The command displays information about the following characteristics of disk drives:
Vendor name Manufacturer of the drive (SCSI only)
Product ID Product identification number or ASCII name
Type Floppy or SCSI classification for the device
Disk Size of disk specified in bytes
Sector Specified as bytes per sector
Both the size of disk and bytes per sector represent formatted media.
Options
The command recognizes the following options:
Return the size of the disk in 1024-byte sectors.
Display a verbose summary of all of the information
available from the device. For floppy drives, this option has no effect.
SCSI disk devices return the following:
Vendor and product ID
Device type
Size (in bytes and in logical blocks)
Bytes per sector
Revision level
SCSI conformance level data
DIAGNOSTICS
Most of the diagnostic messages from are self-explanatory. However, one diagnostic message deserves further clarification. If the command
fails to access the lunpath corresponding to a given special file, it displays the following diagnostics data, which contains device iden-
tification and capability information:
device type 127 (unknown); device is inaccessible
iso ecma ansi rmb dtq resv rdf
WARNINGS
As of release 10.20 of HP-UX, certain IDE devices, CD-ROMs in particular, will respond to inquiries as if they were SCSI devices. There-
fore, the text "SCSI describe" in the output of the command does not definitively mean that the disk is in fact a SCSI drive (especially in
the case of CD-ROMs). Use to check which type of INTERFACE node, SCSI or IDE, the device's hardware path lies beneath, in order to defini-
tively determine a drive's interface.
DEPENDENCIES
General
The command supports floppy and HP SCSI disk devices.
SCSI Devices
The SCSI specification provides for a wide variety of device-dependent formats. For non-HP devices, may be unable to interpret all of the
data returned by the device. Refer to the drive operating manual accompanying the unit for more information.
