DAC defined FSC okay

[DebiJo]

I have a PSeries AIX box running 5.1. It is connected to a FASTT700. I recently received some adapter errors in the errpt. So, everything switched over to the other adapter. What I am seeting now is:

FCS0 available
FCS1 available
DAR0 available
DAC0 available
DAC1 defined

I know I need 2 dac's to go with my 2 FCS's. I tried to do a rmdev on the DAC1 to see if I could run CFGMGR and get it to come back to Available. However, it gives me an error about a dependant device. So, I tried to remove FCS1, since all my disks jumped to my other controller, I didn't expect it to have dependent devices. But obviously, it does.

#rmdev -d -l dac1
Method error (/etc/methods/undefine):
0514-030 Cannot perform the requested function because
the specified device is dependent on another device which is
not in a correct state.

#rmdev -dl fcs1
Method error (/usr/lib/methods/ucfgcommo):
0514-029 Cannot perform the requested function because a
child device of the specified device is not in a correct state.


I can't take the system down til Monday. So I can remove all the hdisks and everything. Any suggestions to do between now and then?

Thanks in advance,
Debi

can you post the output of :

lsdev|grep fc

regrds,

You should do it with following commands:
rmdev -dRl dar0
rmdev -dRl fcs0
rmdev -dRl fcs1
cfgmgr

[DebiJo]

lsdev -C | grep fc
fcs0 Available 1n-08 FC Adapter
fcs1 Available 14-08 FC Adapter

I can't do the rmdev -dR right now for fear that it might remove some hard disks. I will be doing that later this afternoon when I have all the applications turned off.

Thanks!

you can also try just

cfgmgr -l dac1

(would try to reconfiguredac1 - doesn't have to be removed to rediscover/reconfigure it)

or

cfgmgr -l fcs1

(would try to configure fcs1 and all its dependencies)

You don't have to wait until apps are down, but it won't hurt to wait, as you will be playing around with the device database. Note: I do cfgmgr's all the time with systems up and running, but I have no experience with FASTT (only ESS).

I once even added a third FCS adapter to replace faulty paths due to a broken fcs1. A bit hard to remove the faulty paths on the fly, but it is now possible (ESS multipath software now provides for hot-plug PCI capability of the hardware).
