HP NetRAID-4M Configuration and Upgrade Guide (Release 5)

Chapter 9 Issues and Problem Resolution

Problem: If a drive (e.g., drive 0:15:0) was assigned as a failover drive for a

container (e.g., container 01) and then a second drive (e.g., drive 0:10:0) was

assigned as a second failover drive for the same container, the second failover drive

appears at the top of the assigned failover drives list. The assumption is that the first

assigned drive should be the first on the list.

Workaround: No action required. The table of assigned failover drives shows the

drives that are part of the available free space. It just happens that the drives assigned

last are added to the top of the list.

27 Order in which failover drives are used

Problem: Using the example in the previous concern, when a drive is removed from

container #01, the rebuild then starts but instead of using drive 0:15:0 (the first

assigned failover drive), it uses 0:10:0 (the last assigned failover drive).

Workaround: No action required. It just happens that drive 0:10:0 is the first on the

list of drives available with sufficient free space to failover to. The time of assigning

the failover drive is not reflected in this window.

28 Flashing the hard disk firmware

Problem: When flashing the firmware on a certain model of disk drive, on rare

occasions, the flash process will abort with a timeout error message.

Workaround: Repeat the flash procedure and it should be successful the second

time.

29 Disk drive hangs

Problem: NetRAID cards are incompatible with some older revisions of drive

firmware. This could lead to unstable system performance.

Resolution: Update your disk drive firmware to the correct revisions using the

method stated in Chapter 6‚ Disk Drive Firmware Revision.

30 Foreign containers are not being exposed during “Controller Rescan”

Problem: When drives from a different system, with existing containers, are added

to another system, the OS does not recognize them. This occurs in the following

situations:

• When foreign drives with containers are imported to the system.
