Currently i had a server directly connect to the EMC box.
The EMC storage is a FC Direct Attached Storage to the server without going through SAN switches
And i had download theDaily data file in /var/adm/sa/sardd
But i not sure which one in /var/adm/sa/sardd is the correct information i need to get for the I/O report
kindly advise !
Thanks =)

is it the above is the I/O performance data.
but how do i know those sd0, sd1 .... is refer to which device?
please help ! =)
All,
I am attempting to help tune a Sun for better performance (mainly for SAS 9.1), and have found indicators pointing to poor I/O utilization. I have run iostat -cx, and found one device in particular where the %w is in the 90's during processing. I have a feeling that this is where the SAS... (3 Replies)

Hi, can anyone please suggest a tool to dump i/o packets just like tcpdump does for network traffic. Basically I have a complex dataflow that needs to be optimized and I want to see how packets go to/from disk - what goes randomly and sequentially.

A find for the "iostat" command on a redhat 5 update 4 comes back with no results.
Any separate rpm needs to be installed to get the binary for this ?
Thanks in advance. (1 Reply)

Hi Everyone,
I try to calculate the total hard disk space of a solaris machine using iostat -En command. Iterating the output and summing up all the number present near the Size: will give the exact size of the harddisk. But it is not working for a machine.
This command works in many flavors... (2 Replies)

mdbfontsize
mdbFontSize(5) The m17n Library mdbFontSize(5)NAME
mdbFontSize - Font Size
DESCRIPTION
In some case, a font contains incorrect information about its size (typically in the case of a hacked TrueType font), which results in a
bad text layout when such a font is used in combination with the other fonts. To overcome this problem, the m17n library loads information
about font-size adjustment from the m17n database by the tags <font, resize>. The data is loaded as a plist of this format.
FONT-SIZE-ADJUSTMENT ::= PER-FONT *
PER-FONT ::= '(' FONT-SPEC ADJUST-RATIO ')'
FONT-SPEC ::=
'(' [ FOUNDRY FAMILY
[ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
REGISTRY ')'
ADJUST-RATIO ::= INTEGER
FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font.
See m17nFont for the meaning of each property.
ADJUST-RATIO is an integer number specifying by percentage how much the font-size must be adjusted. For instance, this PER-FONT:
((devanagari-cdac) 150)
instructs the font handler of the m17n library to open a font of 1.5 times bigger than a requested size on opening a font whose registry is
'devanagari-cdac'.
