I am looking at upgrading the firmware of our LSI HBAs to P19 since
we suspect that our use of P17 is the cause for disk timeouts we
are seeing every few weeks.
I am wondering, is it save to flash the HBAs from a running omnios system,
and if so, has anyone written some notes down on the process and
tools to use?
I don't believe that is possible on a live system. I have upgraded using
the Solaris sas2flash utility on a system with the pool exported. The
last step of the flash function is to reset the adapter which fails
requiring the system to be rebooted.
What I haven't tried is disconnecting the SAS cables then applying the
update. I suspect this may work, but is only a useful method if you have
redundant SAS paths and can do one HBA at a time.
These issues are why I run HA systems and can migrate my pools from server
to server and perform maintenance at a leisurely pace and confirm
everything is the way I want it before putting the server back in service.
