Install Serviceguard with MSA500
I need to install another Serviceguar with an MSA500 with one scsi per node. No HA for scsi.
The SO is Red Hat Linux 4 u4
My question is:
I need to do something like: mdadm тАУcreate /dev/md0 --level=multipath --raid-devices=2 /dev/sdf1 dev/sdh1
And later with this /dev/md0 I need to make fdisk, later make the pvcreate, vgcreate, lvcreate and mke2fs...
Three months ago, I have installed another cluster with MSA500 and finally all works but I would like to ensure about this point of MDs and LVM, because I`m a bit confuse.
So, thanks a lot, and if you know something more than the manual and reference guide about installing a Serviceguard cluster with MSA500 over RH Linux... thank a lot.
See you,

Re: Install Serviceguard with MSA500
If the MSA500 is older make sure its firmware is up to date before you start any work.
You need to do fdisk partitioning before you do any mdadm work.

Re: Install Serviceguard with MSA500
Where can I found the correct firmware level for the MSA500 with RedHat 4 u4 and Serviceguard 11.16??
If the firware requieres an update. I need to ask for a hardware person in HP.
I'm from HP, but only for software support.
Ok, first of all: fdisk /dev/sda and create a partition type Linux (83)
Then create md
Then create pv in this /dev/md0
Then vgcreate, lvcreate
Thats it?
Thank

Re: Install Serviceguard with MSA500
Look for the manuals:
http://docs.hp.com/en/ha.html#Serviceguard%20for%20Linux
Here is a link for a SW/FW for packaged cluster with MSA500. Don't see any MSA500 FW updates, just for SmartArray HBAs.
You can ask on thw Microsoft Cluster forum (if it exists) about MSA500 FW Someone there may know.
If you areally are talking MSA500 and not teh MSA500G2 realize that this only works in 32bit mode (no x86-64 support).
Cheers

Re: Install Serviceguard with MSA500
So if I understand you:
I dont have to make any MDs so the MSA500G2 take the control of the disk access. Is it?
I'm useing the ServiceGuard guide, and in the page 79 of the manual says to make the MDs.

Re: Install Serviceguard with MSA500
If you do not use this extra hardware, then you should use the disk monitor function. Also make sure you are using the latest version of the documentation.
There is a FW update posted for the MSA500 G2. Follow this link:

Re: Install Serviceguard with MSA500
I have only one SCSI channel... because the customer only buy one SCSI adapter for each DL380 G4.
So in that case, I don`t need to do MDs, because the MSA500 G2 controls the concurrent acces. Wright?
The monday I will go to install RHEL in the customer.
Then I will tell you.
Thanks

Re: Install Serviceguard with MSA500
Almost every MSA type storage unit shipped by HP is behind on firmware within 30-60 days of being shipped.
There were some problems with MSA storage units and HP-UX that made firmware updates very important as multiple HP-UX systems could not connect without a firmware update.
Similar problems may have happened with Linux but I've not experienced them. Part of working with this storage is keeping up to date on firmware for the MSA and fiber channel adapters if you are using this type of adapter.
