HP _Autoraid Disk Balance in Progress

[Eugeny Brychkov]

Some notes on it:
Autorebuild is disabled. If disk will fail array will not rebuild. If one more disk will fail data will be lost. So please better turn on autorebuild and set rebuild priority to low.
BTW, I remember 12h can hold 36GB disks, so you have ability to increase your storage space. But maybe better (and cheaper) to buy VA71x0 disk array?

One more thing............

In /opt/hparray/bin are some tools, specifically logprint. Syntax is

logprint -t perf
logprint -t ctrlr

This will give you performance data and controller errors. The controller error include disk errors so you will know if a disk is going south. The performance data will have to be analyzed by HP in all probability.

Hello,

Yes, the unallocated space is used for RAID 0+1/RAID 5 allocation. In fact, that is why it is recommended to be at least 50% of your whole space. That way, all data will be in RAID 0+1, which means performance gain by:

1. RAID 0+1 is much more performant than RAID 5.
2. No balancing is performed.

Anothr thing. If you want to increase space, increase disks in PAIRS, not 1. This applies if the disks you are entering are larger than your current disks. If you enter just 1 36Gb disk, and you have 9Gb disks, for example, the AuotRAID will only use 9Gb from the 36Gb disk. But if you enter 2 36Gb disks, you will use all the space provided by the disks.

Also, if you are entering 36Gb disks, the fans must be high-spec. If you don't have the fan logo on your fan on a "bubble", but instead on a flat surface, then you need to change the fans in order to install 36Gb disks. This will provide the cooling necessary for these kind of disks to operate.

HTH,
Vince
