Feel toasters will be faster to help... Here is the description of my problem>
I have an 840 cluster running 5.3.5H1 R2. When I initiate a manual takeover from A, it successfully takes over B. However, the reverse is not true. If I initiate a manual takeover from B (cf takeover) it fails and tends to hang A in rebooting stage..Here are the typical error messages.. ___________________________________________ Here is the o/p when I initiate a manual takeover.. ___________________ Tue Dec 19 16:31:52 PST [rc]: Cluster monitor: takeover initiated by operat or Tue Dec 19 16:31:52 PST [cf_main]: Cluster monitor: takeover attempted after cf takeover command Tue Dec 19 16:31:52 PST [cf_main]: Cluster monitor: UP --> TAKEOVER Tue Dec 19 16:31:52 PST [cf_takeover]: Cluster monitor: takeover started Tue Dec 19 16:32:04 PST [disk_admin]: Resetting all devices on ISP2100 in slot 9 Tue Dec 19 16:32:12 PST [raid_disk_admin]: Root volume vol0 has the same FSID as another volume on this system.

You'll need to log a call regarding your cluster failover, but I can answer this one:
I can't use the Windows Hyperterminal keyboard, when console is pluged directly to com port of a windows PC. I was able to do it earlier..but not now..
Don't forget to turn flow control off. 9600 baud, no parity, eight bits, one stop bit, no flow control.

According to the /etc/messages.. your root volume has the same FSID as another volume. This is why it could not do a takeover.
There is an rc_toggle_basic command that will give you a new FSID.. BUT it is the a good ideal to open a case with Network Appliance Tech Support. They can tell the complete step by step process you need to do inorder to fix your problem. If I remember correctly I think you will need to do a reboot..so you might want to look at when your next downtime is available.
