I have several stacks of 3750's (from pairs to a stack of eight) that require IOS updates... almost all are running 12.1(19) and must go to 12.2(35).
thoroughly, but cannot get past a couple issues:
1)from the master, I cannot see the flash of any member, on any of my stacks. I have the option of 'sh flash', and 'sh flash1', both of which are identical (switch 1 is master), but sh flash2, which should show me the flash of the member (when I have a pair) will always fail.
On my stack of eight 3750s, I have the option of flash and flash8 (switch 8 is the master)... nothing else. Nothing in between.
Therefore, I do not have the ability to tftp the new IOS to the member switches... only the master.
2) Auto-update has never worked. Once I set the boot system switch all path to the new IOS and reboot, members will always come up in version-mismatch.
Again, from the link, the command to 'copy IOS flash2' will not be usable, as flash2 is not an option. I'm left with no choice but to break the stack, tftp the IOS to the member (which is now its own master), set the boot path, and reconnect the stack.
I have a couple questions for anyone running 3750 stacks:
Can you view the flash of your member switches?
Can you tftp to your members?
Have you tried the batch IOS update process, and been able to set the 'boot system switch all flash:path' and had success?
I have seven more stacks to go, so any suggestions/links would be greatly appreciated.
