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 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)

sgpio - captive backplane LED control utility
SYNOPSIS
sgpio [-h] [-V] [[-d|--disk <device>[,<device>...]] | [-p|--port <port>[,<port>...]]] [-s|--status <status>] [-f|--freq <frequency>]
DESCRIPTION
Serial General Purpose Input Output (SGPIO) is a communication method used between a main board and a variety of internal and external hard
disk drive bay enclosures. This utility can be used to control LEDs in an enclosure. For more information about SGPIO, please consult the
SFF-8485 Specification.
OPTIONS -h, --help
displays a short help text
-V, --version
displays the utility and AHCI SGPIO specification
-d, --disk
disk name of LED location. Names are sda,sdb,sdc,... Multiple names can be provided in a comma-delimited list.
-p, --port
SATA port number of LED location, can be used if a disk name is no longer valid. 0,1,2,3,... Multiple ports can be provided in a
comma-delimited list.
-s, --status
status of the LED to set. LED status is: locate, fault, rebuild, off
-f, --freq
Set the frequency at which the LED should blink (in Hz). Frequency should be an integer between 1 and 10.
EXAMPLES
Set the locate LED on SDA with an Intel Intelligent backplane:
sgpio -d sda -s locate
Set the locate LED on SDA to flash at 3 Hz for non-intelligent backplanes:
sgpio -d sda -s locate -f 3
Set SATA port 2 with fault at a 3 Hz flash rate:
sgpio -p 2 -s fault -f 3
Set disks sda through sdf to fault:
sgpio -d sda,sdb,sdc,sdd,sde,sdf -s fault
EXIT STATUS
sgpio should return zero when successful. It will return with a non-zero value if there was a failure.
