Migration considerations

Find information about upgrading from PCI-X and PCIe SAS RAID storage adapters to PCIe2 or PCIe3 SAS RAID storage adapters

Before you install the PCIe2 or PCIe3 SAS RAID storage adapter, ensure that you have a current data backup. Before you upgrade the adapters, ensure there are no existing adapter or array-related errors.

The PCIe2 or PCIe3 SAS RAID storage adapter verifies that the arrays are able to be converted and if not, will log errors. Once these errors have been corrected, the adapter starts the conversion automatically. Each data block in the attached disk drives (HDD/SSD) is converted to the T-10 data integrity field (DIF) format. The RAID sets remain unprotected during the conversion.

When upgrading from PCI-X and PCIe SAS RAID storage adapters to PCIe2 or PCIe3 SAS RAID storage adapters, ensure that the hard disk drives (HDD) and solid-state drives (SDD) are at the current, supported code levels. The RAID sets remain unprotected during the conversion.

Check the IBM® prerequisites site for the supported Operating System (OS) levels. Also, ensure that the HDD and SSD drives are at the current supported code levels.

Note: Once this conversion is performed, the devices are not useable on the previous PCI-X or PCIe SAS RAID storage adapters unless they are reformatted.
