QLA Linux and RDAC - Sun 6140 Failover

| | Comments (6) | TrackBacks (1)
Accessing a Sun StorageTek 6140 array with multipathing (failover) via Fiberchannel from a Linux host is not so easy (You'll dream about having scsi_vhci MPxIO out of the box in Linux...).

First: The Sun StorageTek 6140 does not support symmetric multipathing - only one path and controller is active for a given volume. When trying to access the volume on another path SCSI errors are the result. So the failover code has to talk to the array if it whishes to change the active path.

Second: Linux (with actual Q-Logic drivers) offer two multipathing strategies and none of them is usable with this Sun arrays:

The entire blog including archives has been converted to UTF-8.
I hope all works well now.
In case you do not see cyrillic characters in the headline (which mean a formal "Hi!" or "Hello" in the russian language) there's still a mistake....

Articles aussi en français?

Une question: Est-ce qu'il y a un interêt parmi-vous de lire des articles sélectionnés aussi en français?

Je n'aurais pas le temps de formuler toutes les entrées de ce blog aussi en français mais pour les textes instructifs je me sens capable de le faire.

Le français est ma deuxième langue maternelle (allemand étant la première). J'ai débuté ce blog en anglais car il y a beaucoup plus de personnes dans le monde qui comprennent l'anglais que ceux qui comprennent le français. Et j'ai voulu améliorer mon anglais médiocre.
J'ai travaillé en afrique francophone et en France et je connais beaucoup de mots francophones pour les termes d'informatique.

Qu'en pensez-vous?

Due to popular demand, here are part two and three about basic fiberchannel configuration & diagnostics in Solaris. So the basic trilogy is ready:

Part 1: Introduction, Basics
Part 2: Configuration SAN & TCP/IP
Part 3: Diagnostics

I hope it helps you.

And they put a simple (not to be taken too seriously) test on their webpage:

http://media.mi6.gov.uk/selfselect/sis.html   (Flash required).


And no, the test won't ask you about the style of young women nor on data of expensive fast cars. It is a test where you have to remember as much facts as you can of an entry statement describing your identity for a mission.

Have fun!

PS: I had 8 right answers out of eight. But - as the website states - this funny test is not to be taken as application ;-) (and I am not british anyway...). How many points did you have?
