# iostat -xdmzC 1 10 | egrep -v "sd|md|nfs"

# fcinfo hba-port | grep -i wwn

For this you can use the ethtool

ethtool -p ethN

example:

ethtool -p eth0

One or more LEDs on the specific physical ethernet port are blinking now.

1. Make de keys using ssh-keygen

On the “Enter passphrase” question leave black and enter.

# ssh-keygen -t dsa -f ~/.ssh/id_dsa
Generating public/private dsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/user1/.ssh/id_dsa.
Your public key has been saved in /home/user1/.ssh/id_dsa.pub.
The key fingerprint is:
87:52:b6:ec:c9:1f:f2:ce:be:d7:33:e9:1b:2b:33:dd user1@myserver1

2. Copy the public key for the server you want to have direct access.

# scp .ssh/id_dsa.pub user1@myserver2:~/.ssh/authorized_keys_temp

On myserver2 increse autorized_keys

# cat ~/.ssh/authorized_keys_temp >> ~/.ssh/authorized_keys

Remove temporary authorized_keys

# rm ~/.ssh/authorized_keys_temp

TIP: On RHEL 5 You can use ssh-copy-id

# ssh-copy-id -i ~user1/.ssh/id_dsa.pub user1@myserver2

1. Install rsh-server

2. Enable services

# chkconfig rsh on
# chkconfig rlogin on
# chkconfig rexec on
# chkconfig nscd on
# chkconfig xinetd on

3. Reestart xinetd and  nscd

# /etc/init.d/xinetd restart
Stopping xinetd:                                           [  OK  ]
Starting xinetd:                                           [  OK  ]

# /etc/init.d/nscd restart
Stopping nscd:                                             [  OK  ]
Starting nscd:                                             [  OK  ]

4. Edit /etc/securetty and add rsh, rlogin and rexec

# vi /etc/securetty

Put on end of file:

rsh
rlogin
rexec

5. Create file ~user1/.rhosts (user1 is my user example)

# vi ~user1/.rhosts

Put on end of file:

myserver2 user1

Change the permission of file

# chmod 600 ~user1/.rhost

6. Testing

On myserver2 with user1 create a file testing.file

# touch testing.file

Uses the rcp:

# rcp testing.file myserver1:tested.file

Look if file are created using the rexec

# rsh myserver1 ls -l ~user1

This is my first AppleScript. It’s not beautiful, but works fine.

With this AppleScript you can manager multiples conections using iTerm.
This AppleScript make automatic connections and commands using a file text on $HOME/iTerm-CM/Services. Please read Usage.

Usage:

Create on your home the dir iTerm-CM and put a file server (full path $HOME/iTerm-CM/servers)
The file need content that structure:
SERVERNAME:ADDRESS:USERNAME:PASSWORD:CMD1:CMD2:CMD3:CMD4
The script open a server list, select server and enjoy

For more informations, look here.

First identify your installed or recognized

# lspci | grep -i fibre
04:00.0 Fibre Channel: QLogic Corp. ISP2432-based 4Gb Fibre Channel to PCI Express HBA (rev 03)
04:00.1 Fibre Channel: QLogic Corp. ISP2432-based 4Gb Fibre Channel to PCI Express HBA (rev 03)

On Red Hat Enterprise Linux 5 (5.x) is on /sys/class/fc_host/hostX/port_name

(X is your device 1,2,3,…N)

For get use:

cat /sys/class/fc_host/hostX/port_name

Sample with multiple HBA (Fibre) QLogic

# ls /sys/class/fc_host/
host3  host4  host5  host6
# cat /sys/class/fc_host/host[3-6]/port_name
0x2100001b32936e24
0x2101001b32b36e24
0x2100001b32932821
0x2101001b32b32821

On Red Hat Enterprise Linux 4 (AS/ES) is on /proc/scsi/qla2xxx/1 (1,2,3,..N)

Sample:

# egrep [node|port] /proc/scsi/qlx2xxx/0
scsi-qla0-adapter-node=200000e08b1c19f2;
scsi-qla0-adapter-port=210000e08b1c19f2;

Searching about NMON I find the SARMON. This is a great solution for reports of capacity on Solaris.

If you know the NMON (website) for AIX e Linux and need for Solaris you can use the SARMON (website)

For reports you can use the original tool

The installation is very ease

1. Get the .zip file

2. Save on /var/tmp

3. Unzip the .zip

# unzip sarmon_v1.01.bin_sparc.zip

4. Make backup of original files

# cp /usr/bin/sar /usr/bin/sar.orig
# cp /usr/bin/timex /usr/bin/timex.orig
# cp /usr/lib/sa/sadc /usr/lib/sa/sadc.orig

5. Move the sarmon to /usr/local

# mv /var/tmp/sarmon_v1.01.bin_sparc /usr/local/sarmon

6. Copy files

# cp /usr/local/sarmon/sar /usr/bin/sar
# cp /usr/local/sarmon/timex /usr/bin/timex
# cp /usr/local/sarmon/sadc /usr/lib/sa/sadc

7. Edit the crontab and put the entry for collect

0 0 * * * /usr/local/sarmon/sa1 300 288 &

This start collect every day at 00:00

The files generated are in /var/adm/sa/ (day-by-day)

1. Open one SSH on XSCF

3. Verify your top disks I/O with iostat

Sample:

[root@MYSERVER ]#  iostat -xM | grep ssd

4. Verify the SSD Devices on XSCF of respective domain of server.

Sample:

# showdevices -v -d 01
01  01-2      ssd201  /dev/dsk/c4t500009740809C55Cd42s2Device being used by VxVM
01  01-2      ssd202  /dev/dsk/c4t500009740809C55Cd41s2Device being used by VxVM

1. Umount all filesystems used

# umount /myfilesystem1
# umount /myfilesystem2

2. Stop all volumes of Disk Group (DG)

# vxdg -g DG_APPS stopall

3. Deport the Disk Group (DG)

# vxdg deport DG_APPS

4. Import Disk Group with new name

# vxdg -n DG_DB import DG_APPs
