Hi,

I've installed HMC (6.2.1), open network, 128.200.91.15, one NIC to p650-6M2 AIX 5.2 (128.200.91.5). I can access HMC remotely, I can ping HMC from AIX and vice versa. I can add AIX from HMC if I use Console | Add host.

But I CAN'T add the AIX if I use Server Management | Add Managed System. It will show fine, but the state is Not Connected. I need this option so I can remotely shut down and power on the server.

hscroot@hmc:~> lssysconn -r all
resource_type=sys,type_model_serial_num=unavailabl e,sp=unavailable,sp_phys_loc=unavailable,ipaddr=12 8.200.91.5,alt_ipaddr=unavailable,state=No Connection,connection_error_code=Connecting 0000-0000-00000000

Unfortunately, the server is in Colo 50 miles away so I can't check the serial cable. IBM support site suggests to reset the processor on managed system, by shutting down the server and unpluging the AC. I can't do that because it is a production system. I've tried restarting the HMC but without any luck.

Any help appreciated.

Thanks!

Hi

AFAIK the p650 server connects to the HMC using a serial cable to the serial port, not a network one.

Hope this helps

You are right. I've learned this hard way.

Now, I have another problem. It seems that HMC 6.1.2 dropped the support for serial ports. You can't manage the serial ports from HMC. And if you want to add a managed server the only choice is to use IP address.

I wonder if HMC 6.1.2 supports serial ports. Most likely I will downgrade.

Thanks

No the hmc code at 6.1.2 only supports power5 systems and ip connection to the service processor.
You need to install power4 HMC code, the latest is 3.3.7, and a serial connection to the p650.

I tried to downgrade from v6 to v3. After I installed the first CD, it prompted to insert the second CD, but after the restart I got grub prompt instead of booting from the second CD. I made sure that boot from CD is the first option in BIOS, so I have no idea why I got this grub prompt.

I put Windows 2003 server CD and booted in Recovery Console. I did fixboot and fixmbr, also doing format C: on HMC.

Then I installed the first CD again and after the reboot it booted fine from the second CD. Everything looks OK now.

Thanks everyone
