Mc/Service guard configuration

[subhashpakhare]

Dear Experts.
we are having 2 2405 servers & we wanted to configure them in cluster using mc/service guard & we are planning to buy ds2300 as a external storage which is supported in Mc/service guard configuration,
Does anybody have this configuration,please let me know what else components we have to buy for this configration?how we will do raid configration?
Please advice me since i am new in clustering..!

DS2300 is a JBOD. So you should have MirrorDisk/UX software for configuring RAID volumes.

For cluster configuration refer,

I've read info for the DS2300 and assume it's a jbod, but there wasn't anything in the specs or info online about it. The DS2100 and 2110 said raid was avail only through software solution or a pci raid controller.... so I'd have to guess the DS2300 is the same, but a sales rep should be able to answer this.

you can use LVM or VxVM for s/w raid, or look into HP 4si RAID controller.

Thanks Karathik
what HBA i have to use for this configuration? Normal SCSI Card or can i use RAID 4Si controller?

Thanks lots

If you are looking for a hardware raid solution, use the 4si RAID controller. It'll work with your rp2405....

I can't say I've set this up or used it, but there are docs and release notes out there. Have a look at docs.hp.com and search for 4si RAID. rp2405 specs are also here:

hope this helps,

Ok that means i have to have 2 Raid 4si controllers ?how i will able to configure this in MC/service guard.
Please advice me what HBA's I have to use to acces ds2300 in cluster useing 2 nodes.

[melvyn burnard]

Raid 4SI controllers do NOT support Multi Initiation, (shared discs to you and I ) and are therefore not suported for shared storage in a Serviceguard cluster.
This card is also aimed at lower end systems/environments, and not HA environments

Thanks lots for responses,
But could any body please give me which scsi controller i have to use to acces ds2300 from servers.
