Question : Problem: WTF's up with my iSCSI network config ???

Experts:

I just purchased an EMC AX4-5i dual-SP SAN appliance; two racks, one for SAS drives and the other with SATA drives. I'm just setting up the appliance and I'm stuck, hoping you all can help me figure something out.

If you look at the attached file you'll notice my vanilla setup: 1 server with 3 NICs connected to a pair of GigE switches configured in a meshed network connecting a pair of SP units, each with two iSCSI ports of their own.

The problem I'm having is that on the server i can only ping one of two switches and only two of four iSCSI ports

So before I go any further and start configuring iSCSI initiators or LUNs, etc...I wanted to clear up this networking mystery


Thanks,

Answer : Problem: WTF's up with my iSCSI network config ???

follow these steps to change the storage parameters:

1. at the command prompt:

IMP userid=<user/password> FILE=<export file> FULL=Y INDEXFILE=<some file that you can find>

this will NOT do the actual import but instead generate a file specified by INDEXFILE parameter that contains DDLs definition for all the table, constraints, and indexes.

2. Modify this file to change the tables storage parameters , and save it .
3. at the SQLPLUS window, run this script to create all the tables.
4. after that, run the import again, only this time:

IMP userid=<user/password> FILE=<export file> FULL=Y IGNORE=Y

the parameter IGNORE=Y means that the import will not generate errors even if the tables have been created.

hope this helps.
