This really isn't the SAS address, but it is similar. > c9t5000C50025E5A85Ad0 ONLINE 0 0 0 > mirror-1 ONLINE 0 0 0 > c9t5000C50025D591BEd0 ONLINE 0 0 0 > c9t5000C50025E1BD56d0 ONLINE 0 0 0 > ... > > Is there an easy way to map these sas-addresses to the physical disks in > enclosure ? No. But there are several ways to map them. The easiest is to get the disk serial number and cross-reference to the fmtopo output. I've got a script that does this for NexentaStor. Perhaps someone can port to Solaris (NexentaStor has a utility, hdddiso, that provides disk info, such as the serial number, that is easily parseable in a script :-) fmtopo can talk to many enclosures (run with root privileges) and can get the mappings. A typical line looks like: hc://:product-id=QUANTA-Storage-JB7:server-id=:chassis-id=50016360001d0008:serial=WD-WMAY00547508:part=ATA-WDC-WD2003FYYS-0:revision=1D01/ses-enclosure=2/bay=21/disk=0 If you have more than one enclosure, each enclosure is enumerated, but the cross-reference needs to be done elsewhere (hint: use chassis-id) In these cases, there is an assumption that the "bay=21" logical representation correlates to the silk-screened labels on the enclosure. This assumption can trip you up. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
