WARNING: Page83 data not standards compliant EMC SYMMETRIX 5771

I'm trying to setup mpxio on solaris 10 , with backend storage from DMX 3000.
MCode 5771. after manually set the /kernel/drv/fp.conf and scsi_vhci.conf, and stms -e -D fp , and rebooted. I noticed /var/adm/message shows:

WARNING: Page83 data not standards compliant EMC SYMMETRIX 5771

question: what this warning means? how to correct this? MPXIO somehow is not working as expected? Do I miss something? DO I need "reboot -- -r " reconfiguration reoot for MPXIO to kick in?

Thanks.
JasonJ

I apologize if this is not what you are asking but I figure it's worth a shot.

The SPC-2 port flag in the Symmetrix related to SCSI-3 compliance that affects the output of SCSI page code 0x83 output. Here is some information I received from a Symmetrix expert.

When the SPC-2 flag is not set, Symmetrix reports VPD page 83 according to the SCSI-2 spec, circa 1994. When the SPC-2 flag is set, Symmetrix reports the page according to the SPC and SPC-2 and SPC-3 specs, which are more recent. The four bytes describe the identifier format, purpose, and issuing authority.


The format is documented in each of those specs. See, for example, http://www.t10.org/ftp/t10/drafts/spc2/spc2r20.pdf, section 8.4.4, especially table 171 et seq.

thanks for answering my quetion. here on my system:

bash# symcfg -sid xxxx -sa 08C -p 0 lsit -v | grep SP2
SPC2_Protocal_Version(SPC2): Disabled

my question are:
1. is the message just a warning , that can be ignored? or would it best to enable SPC2 on the FA port?

2. would enable this flag would affect all host accesing storage through FA port? what would be the implication on SCSI behavior on other hosts (on FA port) that are not using MPXIO?

thanks again.
