Powerpath
Hello,
We are running EMC PowerPath 5.1 on a Solaris 5.8. We have two storages connected to this server. We use the disks named emcpower0c to emcpower9c, where emcpower0c to emcpower4c is on the first storage and emcpower5c to emcpower9c is on the second storage. The first storage will be disconnected from the server, so the disks emcpower5c to emcpower9c will be renamed after the server reboot to emcpower0c to emcpower4c, right??? But all the apps are linked to emcpower5c to emcpower9c... is there anyway to save this configuration and after the reboot the system keep working pointing to those devices?? Sorry the english, and thanks any help! If more info is necessary, just ask!! C ya |

Powerpath
We use the disks named emcpower0c to emcpower9c, where emcpower0c to
emcpower4c is on the first storage and emcpower5c to emcpower9c is on the second storage. First off, use of the emcpower-- devices is not required on Solaris. You can continue to use the typical cXtXdX devices. The first storage will be disconnected from the server, so the disks emcpower5c to emcpower9c will be renamed after the server reboot to emcpower0c to emcpower4c, right??? No changes are made to emcpower devices unless you execute a "powermt config" command, so you shouldn't have troubles with just a reboot. I'm pretty sure, even then, that when removing devices the emcpower-- names will remain the same-- although, I'm not 100% on that. But all the apps are linked to emcpower5c to emcpower9c... is there anyway to save this configuration and after the reboot the system keep working pointing to those devices?? You should be fine for a simple reboot. Moving forward, I would switch to using the typical cXtXdX devices-- this is a best practice with Solaris & PowerPath (unless things have changed since I last read the docs). Second, take a look at using "Persistent Binding"; there's a lot of information about this on powerlink in the Solaris Host Connectivity Guide, and the HBA specific documentation (all available on Powerlink).
