Hi Luke Many thanks for the information. We are still awaiting a decent time to perform the upgrade and hope to have a go in the next couple of weeks on a test machine first.
We will indeed only be using one switch and single channel hba cards, so with luck it should be a more straight forward process, but we shall see :) Thanks again for keeping me updated. It's very much appreciated.

Our configuration is as follows: One Emulex dual channel fiber card, with port 0 connected to switch 1 and port 1 connected to switch 2 Each drive is connected from port 0 to switch 1, and port 1 to switch 2 So, when we rebooted the system to create the new /dev/rmt entries we showed 20 *st entries. �Here's an example of what we see, you can see that Drive 1 has four st entries (stepped by a value of five for each one): DRIVE 1 Drive Name: DRIVE1 WWN: 50050763000072A8 Serial Number: 0000000CB518 7st -> ../../devices/[EMAIL PROTECTED],4000/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED],0:st Drive Name: DRIVE6 WWN: 50050763000072A8 Serial Number: 0000000CB518 12st -> ../../devices/[EMAIL PROTECTED],4000/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED],0:st Drive Name: DRIVE11 WWN: 50050763000072A8 Serial Number: 0000000CB518 24st -> ../../devices/[EMAIL PROTECTED],4000/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED],0:st Drive Name: DRIVE16 WWN: 50050763000072A8 Serial Number: 0000000CB518 29st -> ../../devices/[EMAIL PROTECTED],4000/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED],0:st Essentially there were four *st entries for each drive, two for those going through ports on switch 1, and two for ports on switch 2. �I called tech support to find a way to determine how to setup for failover, but automatic failover on the drives isn't support in Solaris. �So, we defined a drive for each st entry (drive1 - 20) and defined a path for each entry. �We then were able to see which drives were using the same ports by correlating the drive serial number with each drive entry. �At that point, we offlined all but five entries, keeping two over fiber channel path 0 and three over fiber channel path 1 to utilize both switches (probably not necessary, but why not?). �If you're only using one switch with a single channel hba I don't believe you'll have any problems. �Let me know if you need any assistance or if this is unclear at all. �Good luck!
