Any one knows what is the best performance average to backup AIX Lpar trough SAN Client, i been applied buffers and number buffers for ft, but the performance is about a 200 MB/sec.
Netbackup Appliance and AIX lpar are connected by brocade switch with 8gb ports, the lpar has independent hba from the vios.
The appliance version is 220.127.116.11, i try to backup a Oracle Database with size 5.6 TB and take about a 8 hours to backup, the compatibility matrix between OS, Oracle Database is OK. Any Ideas ??
First, I'm not sure that backing up an AIX LPAR even with a dedicated HBA is supported.
Are they on the same switch?
Are you seeing any other issues on the appliance?
What log did that come from? There's no indication that it is related to what you're experiencing.
Are you seeing any waiting for buffers in the job details?
The message ""System Firmware Error #0x06 | Unknown Error | Asserted" has been found on /var/adm/messages.
Yes in the job appears as this message "dbclient waited 37140 times for empty buffer, delayed 206657 times"
Any ideas to improve performance ?
Any one knows what is the better performance speed over San Client ?
Someone find one explanation to this case? I have the same problem with any backups that I start.
Tech Note used to test the Netbackup performance
After run all tests I checked that appliance is not writing so fast that san client is send the information
I was having very poor performance with SAN client. Applying the EEB in the technote below appears to have solved it. Note, you have to disable SAN client reboot the appliance, then enable and reboot. The doc says you dont need the second reboot.. I did.
Let me know if this helped..
Hello Every Body,

This is the second chance we try to implement the SAN Client backups from HP-UX San client to Netbackup 5230.
In the first time we applied this technote:
An Emergency Engineering Binary (EEB) is available to resolve Fibre Transport performance issues on NetBackup Appliances.
Updated: July 3, 2015
Article URL: http://www.symantec.com/docs/TECH227091
But nothing changed.
In the second time we faced the same problems and no success.
Any advise in how to solve this issue?
