Hello, I am trying to setup LDOM in more fault tolerant way, and hope someone could help me with this long list of queries.
1. My understanding is, when primary domain goes down all guests drops its network and SAN connection. Looks like alternate i/o domain is the solution for this issue. Please suggest if there is another way. 2. Could someone provide some documentation on creating alternate i/o domain on T5440 host. 3. VCS installed in control domain doesn't seem to support Alternate i/o domain . Looks like when VCS is configured to failover guests, failure of primary or its resources like network or storage would trigger failover of the guests, and an alternate i/o domain is not really required. Please correct if I am wrong. 4. Can I configure VCS to Failover of 'guest domain and application' while guest domains are booting off internal disks. Book says both ldoms must boot from shared san disk. This configuration is mentioned in the book as "VCS is installed in the control domain of each node, and single node VCS is installed on each guest domain." 5. While using the above vcs configuration, can guests have its root disk as ufs or zfs ? Does symantec support it ? Thanks in advance Arjun
