Problem integrating EMC CX3-20 to Sun T5220 server - Wrong partition?

Question

Hi All,
I have a problem integrating the EMC CX3-20 to Sun Sparc Enterprise T5220 server.
In the EMC, two LUNs were created. 1.6TB and 10G were allocated respectively. They were represented by emcpower0a and emcpower1a in Solaris 10.
I'm wondering why the format -> partition command shows different information for the two LUNs.
The partition command on emcpower0a shows the "total disk sector available". But the command on emcpower1a shows "the total disk cylinder available"
I can't use the the disk emcpower0a in Veritas because slice 2 (s2) was not displayed when the command "vxdisk list" is executed. It show "emcpower0" instead of "emcpower0s2".
Can someone let me know how to solve this problem? Appreciate your help. Thanks.
Regards,
Ryan

This is related to the size of the 1.6 TB device. The different disk label you are getting is the newer EFI disk label, which Solaris requires on all devices larger than 1 TB. SunSolve doc 216611 explains the differences between the older VTOC label and the EFI label, and links to the VxVM 4.1 Release Notes for Solaris:
http://seer.entsupport.symantec.com/docs/275690.htm
Veritas began support for EFI-labelled devices with VxVM 4.1, for Solaris 10 only, but you must be on Sol 10 since you're on a 5220.
