I went to a computer store and the salesman sold me a SATA cable and told me that all SATA cables are the same. Another salesman at a different store told me a cable rated for SATA 2, which I bought, MIGHT work as well as one rate for SATA 3 but it is not guaranteed. I decided to run a speed test on my SSD drive to check the results.
I can verify from dmesg and /var/log/messages analysis that I am connected a 6.0gbps. Are my results consistent with that type of connection?
i purchased, what was labeled as a 4-port fast ethernet sbus card from ebay.
i installed it in my ultra1, and it seems to be working fine. how can i determine if the card is infact a fast ethernet card vs. the standard ethernet 4-port card? (7 Replies)
I am trying to find a command to return the "link" speed of the networks installed on AIX.
ifconfig - gives me where the link is up and the duplex setting. I need to determine for example if the ethernet connection is 10, 100, 1000 Mbs or what the current speed is based on the network media... (3 Replies)

Hi guys
I have a bunch of x4100's x4140's etc with solaris 10 update4 running on them but I suspect that when a lot of these boxes were originally built, the jumpstart process used an update2 miniroot, now as far as i understand it, the miniroot used at jumpstart is the miniroot that stays on... (1 Reply)

Obviously, getting the host is simple with hostname. But how... (4 Replies)
Being a novice user to linux i m little unaware of how would i check disk read write speed.
One of my mate is suggesting to create a file using dd command and check how much time it takes to create a 30 gb file .
I think this has a little sense however i would also like to take your reviews... (5 Replies)
Hello all,
I have a question about what you think the best practice is to determine what region you are running on when you have a system setup with a DEV/TEST, QA, and PROD regions running the same scripts in all.
So, when you run in DEV, you have a different directory structure, and you... (4 Replies)

sgpio(1) USER COMMANDS sgpio(1)NAME
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.
