Importing and Exporting Storage
In an environment where there is a storage administrator and a systems administrator, there are some best practices and procedures for importing and exporting disks between hosts. Each administrator has some distinct responsibilities.
AIX Administrator
Releasing a volume and volume group
- Unmount the filesystem.
- Vary off the volumegroup.
- Export the volumegroup.
- rmdev the associated vpath or dlmfdrv's.
- rmdev the associated hdisks.
Removing 1 hdisk from a volume group
- reducevg hdiskN.
- rmdev the associated vpath or dlmfdrv's
- rmdev the associated hdisks.
Receiving a new volume
- run cfgmgr.
- Verify that newly imported hdisks do not have a conflicting PVID.
Storage Administrator
- Re-allocated storage should be re-formatted on the subsystem before releasing to systems administrators. This ensures that confidential data does not flow from one group to another, and prevents PVID conflicts.
- Extra care must be taken when re-allocating ShadowImage volumes. There is the potential for PVID conflicts because the copy has the same PVID as the source.
