Greetings, I'm curious if anyone might have a plausible explanation to some strange behaviors I see between various Solaris 10 systems running on Sun X64 hardware.
We have a couple of EMC Symmetrix and Clariion SANs, and 20 or so Sun Fire X4200 and X4600 servers. They all run Solaris 10, most of them are also running Sun Cluster 3.2. I believe they all have Sun branded emulex HBA's as well, and we are using PowerPath (for reasons I am unaware of). In my experience, when adding new LUNs to these machines, the X4200s (probably a mix of M2's and not) seem to be very capable of picking up the new LUNs using devfsadm and powermt config. The X4600s (definitely not M2's) do not seem to be able to discover new LUNs and require the old reconfig reboot in order to pickup the new LUNs. Our other Admins have reported that the X4200s also tend to discover nothing new, but I have not personally witnessed this. I have not seen any messages in /var/adm/messages that would indicate failure or error while trying to discover the new devices. Devfsadm -v shows no output when it doesn't find anything new. Can anyone offer ideas as to why this seems to be the case? Our current theory has us wondering about HBA firmware levels between the servers. Thanks. -- This message posted from opensolaris.org _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
