Do you have a default pool on the virtual server? If not, try adding one to see if the error goes away.

When using the session or persist commands, one common error that occurs is "Prerequisite operation not in progress". The most common cause for this error is that there is no pool currently selected for the connection. Persistence and session entries by default are limited to a single pool. For most virtual servers, a default pool is specified in bigip.conf, and this pool will be used when persistence or session queries are made. Selecting a default pool to use is usually the best way to eliminate this error. If you cannot specify a default pool (for example, with a forwarding virtual), then you can specify that the operation should be across all pools using the any pool option described above.
