[stgt] how to set VPD page 83 (Device Identification) using pacemaker

[Doug Clow]

Thanks Alexander, I'm looking forward to trying it out.  Good question, I'm not sure where it got the first part of the VPD serial number.  The only other MS documentation I could find is this:

https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CDAQFjAA&url=http%3A%2F%2Fdownload.microsoft.com%2Fdownload%2F3%2F2%2Fc%2F32cb69db-71e3-447e-a91b-4070cdc4548a%2FMicrosoft-iSCSI-Logo-Requirements-1.0.doc&ei=ULmKUeaLGeOYiQKX04DAAg&usg=AFQjCNGq3o7P1o_XiYH2Fuq3tmd0UzIbVQ&bvm=bv.46226182,d.cGE&cad=rja

which has this information on VPD in it (although it seems general and not specifically for Failover Clustering):

g.	Required Vital Product Data (VPD) pages: 0 Supported Pages, 80h: Serial Number, 83h: Device IDs. 
i.	For VPD Page 83, type 2 or type 3 descriptors must be returned and must be unique for each logical unit. Appropriate descriptors for multiport devices are required in addition to the type 2 or 3 descriptors. Devices that support aliases must also support the corresponding descriptor types. Vendor-specific device identifiers, if present, must use type 0 and follow the specified format, including correct page length; vendor specific identifiers are not a substitute for the mandatory type 2/3 descriptors.
ii.	Page 80h (serial number) must be in ASCII. 


Regards,
Doug
