Description

What logs are required to troubleshoot a Qlogic Fibre Channel switch?


Steps to Follow

The primary data required to troubleshoot a Qlogic Fibre Channel switch is a "create support" for newer switches or "show support" for older switches or anywhere "create support" does not work.

The following shows different methods for collecting data:

##############
"create support"
##############

Assembles all log files and switch memory data into a core dump file(dump_support.tgz) on the switch.

If your workstation has an FTP server, you can proceed with the command prompts to send the file from the switch to a remote host.

Otherwise, you can use FTP to download the support file from the switch to your workstation.

The support file is useful to technical support personnel for troubleshooting switch problems.
Use this command when directed by your authorized maintenance provider.

Examples

The following is an example of the Create Support command when an FTP server is available on the workstation:

SANbox (admin) #> create support
Log Msg:[Creating the support file - this will take several seconds]
FTP the dump support file to another machine? (y/n): y
Enter IP Address of remote computer: xxx.xxx.xxx.xxx
Login name: johndoe
Enter remote directory name: bin/support
Would you like to continue downloading support file? (y/n) [n]: y
Connected to xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx).
220 localhost.localdomain FTP server (Version wu-2.6.1-18) ready.
331 Password required for johndoe.
Password: xxxxxxx
230 User johndoe logged in.
cd bin/support
250 CWD command successful.
lcd /itasca/conf/images
Local directory now /itasca/conf/images
bin
200 Type set to I.
put dump_support.tgz
local: dump_support.tgz remote: dump_support.tgz
227 Entering Passive Mode (xxx,xxx,xxx,xxx,xxx,xxx)
150 Opening BINARY mode data connection for dump_support.tgz.
226 Transfer complete.
43430 bytes sent in 0.292 secs (1.5e+02 Kbytes/sec)
Remote system type is UNIX.
Using binary mode to transfer files.
221-You have transferred 43430 bytes in 1 files.
221-Total traffic for this session was 43888 bytes in 1 transfers.
221 Thank you for using the FTP service on localhost.localdomain.

========================

The following is an example of the Create Support command and how to download the support file to your workstation.

When prompted to send the support file to another machine, decline, then close the Telnet session. Open an FTP session on the switch and log in with the account name images and password images. Transfer the dump_support.tgz file in binary mode with the Get command.

SANbox (admin) #> create support
Log Msg:[Creating the support file - this will take several seconds]
FTP the dump support file to another machine? (y/n): n
SANbox (admin) #> quit

>ftp switch_ip_address
user: images
password: images
ftp>bin
ftp>get dump_support.tgz
xxxxx bytes sent in xx secs.
ftp>quit


Via GUI

1. Point browser to switch IP
2. Select "switch" tab in GUI
3. Select "download support file"



##############
"show support"
##############

Preparing to capture long output:

1. Logon to a sun or other unix system
2. Start a script from the commandline

$ script /tmp/showsupport

# telnet to the switch

> />> OR <
For Putty users:

1. Login to switch using telnet/SSH via putty.exe
2. Log the session output to a file

# term len 0

Then

# execute show support

> show support
> collect data

# logout of the switch

> logout

Then

For sun or other unix system
# break the script session
$ [ctrl-d]
Script done, file is /tmp/showsupport
#

> />> OR <
save log file and exit putty
