Depending on the hardware you are using, you may be able to benefit from croinfo. $ croinfo D:devchassis-path t:occupant-type c:occupant-compdev --------------------------------- --------------- --------------------- /dev/chassis//SYS/SASBP/HDD0/disk disk c0t5000CCA012B66E90d0 /dev/chassis//SYS/SASBP/HDD1/disk disk c0t5000CCA012B68AC8d0 The text in the left column represents text that should be printed on the corresponding disk slots. -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
