planning has been given to any operating-system-related disk layout, such as the AIX Logical Volume Manager, when using disk hot-swap capabilities. For more information, see Problem Solving and Troubleshooting in AIX 5L, SG24-5496.

Note: It is recommended that you follow this procedure, after the disk has been deconfigured, when removing a hot-swappable disk drive:

1.Release the tray handle on the disk assembly.

2.Pull out the disk assembly a little bit from the original position.

3.Wait up to 20 seconds until the internal disk stops spinning.

Now you can safely remove the disk from the DASD backplane.

After the SCSI disk hot-swap procedure, you can expect to find SCSI_ERR10 logged in the AIX error log, with the second word of the sense data equal to 0017. It is generated from a SCSI bus reset that is issued by the VSES to reset all processes when a drive is inserted, and it is not an issue.

Hot-swap disks and Linux

Linux does not support hot-swap of any disk drive at the time of writing, therefore the Linux operating system does not support these hot-swappable procedures. A p5-570 system running Linux must be shut down and powered off before you replace any disk drives.

2.6.2 Internal RAID options

Every p5-570 building block system is delivered with a disk drive cage that supports up to six disk drive units, offering both internal RAID and non-RAID solutions. When internal RAID solution is not required, at least one 36.4 GB 10K disk drive (FC 3273) is required.

The internal RAID solution requires at least three 36.4 GB 10K disk drives (FC 3273) and the SCSI RAID Enablement Card (FC 5709). Other supported disk drives may be ordered in place of FC 3273. When the SCSI RAID Enablement Card is installed in the system, it re-sequences the two SCSI controllers that support the six disk drive bays, transforming the system from two logical 3-packs of disk drives to one physical 6-pack of disk drives.

The RAID implementation requires a minimum of three disk drives to form a RAID array, so when an order comes in place with FC 5709, at least three disk drives must be in the order list.

Note: Because the p5-570 building block has six disk drive bays, customers performing upgrades must plan accordingly to ensure the correct handling of their RAID arrays.

The p5-570 system supports external RAID solutions, and this requires an additional PCI-X adapter (such as the FC 5703) and external disk drives enclosure.

2.6.3 Internal media devices

The p5-570 provides two slim-line media bays per drawer for optional DVD-ROM (FC 2640) and optional DVD-RAM (FC 5751).
