Service Guard & Secure path

[Goran Kubelka]

Dear All,

Is it mandatory to have installed SecurePath for HP-UX on cluster nodes before installing Service Guard?
Both nodes of cluster should have two FC card each connected to srorage in NSPoF configuration.
Is it possible to build HA solution without SecurePath for HP-UX installed on cluster nodes?

Regards,
Goran

Hi Goran

1. Securepath is recommended when you have dual FC paths. It will take care of path failure and provide dyanamic load balancing

2. You can have HA solution without SP. In such case LVM primary and alternate paths have to be defined.

As indicated above SP helps in load balancing and thus better IO throughput.

Securepath is a failover/loadbalancing solution for dual FC paths. It is not necessary for MC/SG.

[Luk Vandenbussche]

Secure path is required in an environment with MC/Serviceguard.
I does'nt matter it you install it before or after MC/Serviceguard. It must be installed before you configure the cluster

Hi,
MCSG and SP are two different areas. SP needed in case your storage requires SP (for example EVA3K & EVA5K SP is mandatory). You can have MCSG with or witout SP. When configuring VGs without SP, make sure you create VGs with alternate links in all nodes.

Note: For EVA4K,6K,8K SP is optional.
For HP VA also SP is optional.
