Hi,
We have two servers in scenario (vmsoldot01 is Oracle VM with Linux and tldtppod15 is physical Linux server). One NAS share is mounted on both servers with similar permissions and access. But READ speed is too bad on virtual in comparison to physical server.
While trying to diagnose this, I see RX-DRP value is high. Can I assume that this is (also) playing role in it ? What else can I check ? Any pointer ?
Hallo,
i need a Prompting read in my script:
read -p "Enter your command: " command
But i always get this Error:
-p: is not an identifier
When I run these in c-shell i get this error
/usr/bin/read: read: bad option(s)
How can I use a Prompt in the read command? (9 Replies)
Hi,
Currently I have a Samba shared configured as follows:
comment = Public fileshare
path = /u02/pub
guest ok = Yes
writeable = Yes
There is a subfolder under /u02/pub called /u02/pub/expenses/hardware that I need to make read only. How do I do this? I am new to using Samba.

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)
I'm hoping someone here can help me. I'm computer literate but by no means an expert! I'm simply trying to recover data from my DLink DNS343 NAS mounted on my X86 iMac using SMB. Somehow, in moving to a new computer, I have lost access to some files on the NAS. Just some files are access denied.

there are few nas shares that would be mounted on the local zone. should i add an entry into the add an entry in zone.xml file so that it gets mounted automatically when the zone gets rebooted? or whats the correct way to get it mounted automatically when the zone reboots (2 Replies)
I have an AIX box that mounts a Windows share across subnets. When I try to copy a 100 MB file to it, it copies around 2 MB/s. If I copy to another Windows share on the same subnet it copies around 12 MB/s. All I have is gigabit networks so I would expect it to go well over 12 MB/s, which is the... (8 Replies)
Heyas
At home i have 1 nas with 3 shares, of which i used to mount 2 of them using a script with hardcoded password and username in it.
EDIT: Turns out, its not the script, but 'how i access' the nas share.. (-o user=XY,password=... VS. -o credentials=...).
Figured about credential files,... (0 Replies)
Hello All,
I am building a real time parser for a log file in my application.
The log file is continuously written at a very fast pace and gets rolled over every 10 minutes.
I have measured the speed and observed that around 1000 lines are written to it every second, each line about 30-40... (7 Replies)

scnasdir
scnasdir(1M) System Administration Commands scnasdir(1M)NAME
scnasdir - manage the exported directories on a network-attached storage (NAS) device in a Sun Cluster configuration.
SYNOPSIS
scnasdir [-H]
scnasdir [-a] [-H] [-n] -h device-name [-d directory [-d directory...]] [-f input-file]
scnasdir -p [-H] [-h device-name] [-t device-type]
scnasdir -r [-H ] [-n ] -h device-name [-d all | -d directory [-d directory...]]
[-f input-file]
DESCRIPTION
Note -
Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor-
mation about the object-oriented command set, see the Intro(1CL) man page.
The scnasdir command manages the exported directories on NAS devices in a Sun Cluster configuration. The device must already have been con-
figured in the cluster by using the scnas command.
The scnasdir command can be used to add directories to a device's cluster configuration, to remove directories from a device's cluster con-
figuration, and to print the directories of a particular device or particular device types.
The options in this command are processed in the order in which they are typed on the command line. The scnasdir command can only be run
from an active cluster node. The results of running the command are always the same, regardless of the node that is used.
All forms of the scnasdir command accept the -H option. Specifying -H displays help information, and all other options are ignored and not
executed. Help information is also printed when scnasdir is run without options.
You can use this command only in the global zone.
OPTIONS
Basic Options
The following options are common to all forms of the scnasdir command:
-H
If this option is specified on the command line at any position, the command prints help information. All other options are ignored and
are not executed. Help information is also printed if scnasdir is run with no options.
You can use this option only in the global zone.
-n
If this option is specified on the command line at any position, the scnasdir command only checks the usage and does not write the con-
figuration data. If the -n option is specified with the -f option, the scnasdir command displays the data that will be processed for
the user to review.
The following options modify the basic form and function of the scnasdir command. None of these options can be combined on the same command
line.
-a
Specifies the add form of the scnasdir command. The -a option can be used to add directories into the device's Sun Cluster configura-
tion.
You can use this option only in the global zone.
-p
Specifies the print form of the scnasdir command. When no other option is given, this -p option prints a listing of all the directories
of all the NAS devices configured in Sun Cluster. This option can be used with additional options to query a particular device or par-
ticular types of NAS devices.
You can use this option only in the global zone.
-r
Specifies the remove form of the scnasdir command. The -r option is used to remove all the directories, or the specified directories of
a NAS device from its Sun Cluster configuration.
You can use this option only in the global zone.
Additional Options
The following additional options can be combined with one or more of the previously described basic options to manage the directories of a
device.
The additional options are as follows:
-h device-name
Use this option to specify the name of the NAS device in the Sun Cluster configuration. The -h option identifies the device and can be
used to remotely access the device by using rhs or telnet.
This device name must be specified for the add, change, and remove forms of the scnasdir command.
-d all | directory
Use this option to list the directories (or volumes) exported on the NAS device to be configured into the Sun Cluster. These directo-
ries must be created and exported on the device before using the scnasdir command. See the documentation for the NAS device type for
procedures for exporting directories.
The -d all option can only be accepted by the remove option, -r.
The directories must be specified by using either the -d option, or the -f option, for the add and remove forms of the scnasdir com-
mand.
-f input-file
Directories can be placed into a plain text file, one directory per line, and used with the -f option. Leading white spaces and tabs
are ignored. Comments begin with an unquoted pound (#) sign, and continue to the next new line. The parser ignores all comments.
EXAMPLES
Example 1 Adding Two NAS Storage Device Directories to a Cluster
The following scnasdir command adds two directories of a NAS device to the Sun Cluster configuration.
# scnasdir -a -h sunnas1 -d /vol/DB1 -d /vol/DB2
Example 2 Removing All of a NAS Storage Device's Directories From a Cluster
The following scnasdir command removes all the directories that are configured for a NAS device.
# scnasdir -r -h sunnas1 -d all
EXIT STATUS
The following exit values are returned:
0 The command executed successfully.
nonzero An error has occurred.
