I'm having trouble with my SAN devices on AIX 5.3 so I would like to remove the SAN devices and HBAs. Then I want to recreate them with cfgmgr and see if this solves my problem.
So I have the following SAN devices:
Step one is removing fcs0 and all child devices with
Next step is to remove fcs1 and all child devices with
and then it stops removing devices so I decided to remove the devices manually.
So this didn't work. Then I tried a reboot but after the reboot I still have the same problems.
To my knowledge, there are no more SAN devices in the system. What is preventing the system from removing dac3, fscsi1 and fcs1? How can I find out and how do I remove these devices?
Looks as if there something still active on this adapter.
Example:
Check if there is a disk for example, that is still varyon or something similar.
It could also be, that the adapter is connected via a PCI Host Bridge (phb) that has to be set to "defined" to let you have the fcs1 removed:
There should be some pci<n> listed, related to the adapter. rmdev -l pci<n> and then try again removing the fcs1.
I don't know these, sorry. Could be. Maybe try stopping them if they take a hold of devices. Else maybe reboot the box and try again before starting any application. The DAC seems to be something left over from SAN storage?
Can try a fget_config -vA to get more info about it.
If you get to reboot the box and the cfgmgr finds all stuff again, maybe have the zonings temporary disabled, get your devices cleaned and then have the zonings enables again. Or maybe just that LUN or whatever that is, can be disabled on SAN side.
1. lsdev -p fscsi1
would like to know what are the devices attached to them disks/tapes...
2. any log in errpt ?
3. Something is holding , even after after reboot, have you looked at /etc/inittab or had a closer look at ps -ef to check if any related process are running
Hope this helps.
