RX6600 - Full with SAS - Use LVM/VxVM RAID/Mirroring or Hardware RAID

[Alzhy]

Also how do I know if I've a SAS Raid COntroller Card? Here's my ioscan.

Does the On-Board RAID Hardware option require a full card and cables or is it just a chip?

Cost prohbitive?

[TTr · Accepted solution]

What you have right now IS a RAID controller but it is the basic one that comes with the rx sas based servers (rx2600, 3600, 66600). With it you can still do hardware raid but only 2 mirrored pairs with one hot spare(that is, 2 raid-1 volumes not 1 raid10). Typically you don't use a hot spare so you have 4 disks in 2 raid-1 pairs and then you get 4 more disk to use in the OS LVM/VxVM mirroring.

These are separate PCI cards (not on board chips) and are on slot

TRr.

How do I carve my Mirrored pair with a hot spare?

Do I do it under an EFI util?

By 2 mirroed pairs - do you mean 2 pairs of disks plus a spare each?

Is it configured similary to a PERC controller on Dells or Smart Array COntrolers on Poorliants?

Thanks.

Here is the manual link:

Some configurations are possible on- or offline, see

Thanks..
Actually found the docu last night. I was able to create under EFI drvcfg 2 Mirrors with a hotspaer each on sasd0 and sasd1. SO I giess my OS is not protected and I have another mirrorset for my DRD or alternate boot.

Now how do I monitorthe health of my array/mirror-sets? Is there an EMS thingy within BaseOE 11.31? Or do I have to write a script to use "sasmgr" to periodically check on the health of the mirrors?

Thanks!

[Torsten.]

There is a EMS monitor for SAS controllers, example:

http://docs.hp.com/en/diag/ems/emd_sas_adapter.htm

[Alzhy]

Thanks Torsten,

But this machine - intended to be used as NetBackup 6.5 Master/Media Server runs BOE March 2008. I think EMS is still an add-on or available only with the higher releases.

I was hoping there's now a free System Fault Management thingy with 11.31 that's different from EMS

[Torsten.]

EMS is (was) always included in online diagnostics. I guess SFM has also a monitor for such things.

http://docs.hp.com/en/5992-4198/ch01s08.html

Since march (I think) SFM is the default, but you can also switch back to online diagnostics.
