HDLM vs MC/SG
Hi guys,
I'm currently having a 4 nodes cluster which is running MC/SG 11.14 on HP-UX 11.11, and uses HDLM 6.0 as multipathing driver.
We are migrating our Hitachi USP to a VSP enclosure. As a support matrix relases by Hitachi I need to upgrade HDLM to version 6.5 to support VSP on HP-UX 11.11. But I also need to upgrade MC/SG to 11.16 as per their matrix. HDLM is only used in the VGs that contains users and apps data. The vglock VGs are not configured with HDLM.
My question is what is the relation between HDLM and ServiceGuard? Do they ask us to upgrade MC/SG in case we have lock disks configured to use HDLM multipathing?
Thanks
