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. -Chip > cheers > tobi > > > -- > Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten, Switzerland > www.oetiker.ch [email protected] +41 62 775 9902 > > _______________________________________________ > OmniOS-discuss mailing list > [email protected] > http://lists.omniti.com/mailman/listinfo/omnios-discuss >
