Information in this document applies to any platform.

Goal

Learn how to restart the vhbaagent without resetting/restarting IOP when vhbaagent is consuming a high amount of memory.

NOTE: Resetting IOP is disruptive to data path - takes devices down. Resetting vhbaagent is not disruptive to the data path.

Solution

1) Log into the Oracle Fabirc Director as user 'admin'

2) Enter into the debug mode

set cli mode debug

3) Enter the IOP

debug iop <card#>

4) See all the process's that are running on this IOP

show process

5) Make a note of the ID and PID of the vhbaagent

ID PID PPID STATE MEMSIZE CPUTIME COMMAND

=>1 530 528 R/A 5.691406 10011 $XSIGOROOT/bin/vhbaagent -devices /dev/cpld:real,/dev/i2c-0:real,/dev/gpio:real,/dev/spi:real,/dev/xg-vh:real,/dev/xg-ql:real -base 50000 -card 3 -slot 7 -inst 0 -chassis 1 -cardname vhba

2 531 528 R/A 5.105469 2124 $XSIGOROOT/bin/chassisAgt -devices /dev/cpld:real,/dev/i2c-0:real,/dev/gpio:real,/dev/spi:real -base 50000 -card 3 -slot 7 -inst 0 -chassis 1 -cardname vhba

6) Stop the vhbaagent

stop process <ID>

7) Restart vhbaagent

restart process <ID>

8) We must now see a new PID for vhbaagent

show process

NOTE: Its only the xvnd agent that is data disruptive as it is also data disruptive to reset an IO Card.
