Directory Server and IBM i IASP support
From i 7.1, the Directory Server on IBM i® begin to partly support Private IASP. Up to i 7.2, the Directory Server on IBM i® can fully support IASP including Private IASP and Switchable IASP.
An independent disk pool, or independent auxiliary storage pool (IASP), is a collection of disk units used by IBM i® that can be brought online or taken offline independent of the rest of the storage on a system, including the system ASP, user ASPs, and other independent disk pools.
An independent disk pool can be either:
- Private: Privately connected to a single system, also known as stand-alone IASPs
- Switchable: Switched between two systems or partitions in a clustered environment
- Database library located in IASP
- Change log library located in IASP
Because LDAP instance configuration files, schema files and configuration library cannot be located in IASP, an instance is not switchable in i 7.1. From i 7.2, all the data referred mentioned can be put into a single IASP, thus the whole LDAP instance is switchable. This is very important for applications that are based on HA(High Availability) technology.
- Before creating instance on an IASP, the IASP must be configured and available.
- Use IBM® Navigator
for i Create
Instance Wizard to create a new instance:
- On System i Navigator, the ASP number and IASP number are both listed in Disk pool for the user to choose.
- On IBM Navigator for i, the ASP Name and IASP Name are listed for the user to choose.
- Change the value of attribute ibm-slapdDbName under cn=Directory, cn=RDBM Backends, cn=IBM Directory, cn=Schemas, cn=Configuration from *SYSTEM to an IASP device name.
- Change the value of attribute ibm-slapdDbName under cn=CHANGE LOG, cn=RDBM Backends, cn=IBM Directory, cn=Schemas, cn=Configuration from *SYSTEM to an IASP device name.
