My friend and colleague here in IBM L2 SAN Support, Serge Monney prepared a "little-helper" article for our clients. It's intended to help you with the Brocade SAN switch data collection in case of a problem. Maybe you even got the link to this article within a case. This is it:
Be prepared to send good logs to your support
Brocade SAN switch have the particularity to have logs with timestamps and logs without timestamps. The logs without timestamps are counters that tell you what is going on or what is going wrong with your frame entering or leaving your switch. To be able to trust the counters we need to set a baseline by clearing the statistics.
Most of the time support needs the following to perform troubleshooting:
- Take a supportsave to be sure to have the data of the current status (see also https://ibm.biz/BdXnNa)
- Clear counter statistics using CLI. CLI usage is necessary, because the graphical interface does not offer the possibility to clear internal counters like "slotstatsclear" does it.
- If you have a logical switches (VF):
fosexec --fid all -force -cmd "statsclear"
- If you do not have logical switches (VF):
- If you have FOS v7.3 or higher (this replaces a. and b.):
- Let the fabric run for up to 3 hours while the problem is visible or go to the next step immediately as soon as the problem is visible.
- Take a supportsave.
How to take a supportsave
- Use Network Advisor. In the menu under "Monitor" select "Product / Host SupportSave":
(You can download a free version of the Network Advisor after you created an account for mybrocade.com)
- Use the “supportsave” CLI command. Be aware: This needs an FTP server to be configured and running on a management workstation reachable by the switch!
This command will collect RASLOG, TRACE, supportShow, core file, FFDC data and other support information and then transfer them to a FTP/SCP server or a USB device. This operation can take several minutes.
OK to proceed? (yes, y, no, n): [no] y
Host IP or Host Name: xxx.xxx.xxx.xxx
User Name: YYYY
Protocol (ftp or scp):
Your FTP server will receive multiple files. Please compress them and give the resulting archive file a meaningful name. For example:
(Collecting data using the web interface will not help , you need to collect supportsave with Network advisor or CLI )
And to IBM...
To upload the package, please make use of our Secure Upload web frontend:
Just use your PMR (preferred), RCMS, or CROSS case number for your upload to let the system even notify the support engineer with an update to the case. It's also possible to upload data on the plain Machine Type / Serial Number, but then there won't be any direct correlation to the case. In the field "Upload is for:" always choose "Hardware" when you upload SAN data collections. The email address is optional but it will send you a short notice as soon as the upload completed successfully and the support engineer will be able to contact you via mail if needed. After clicking on "Continue" you can drag and drop the archive file containing the supportsave to upload it. That's it!
