The slices used are s0 , s1 , s3, s4, s6 and s7 and these are used to creat the mirrors d0, d1, d3, d4, d6 and d7 So: c1t0d0s0 and c1t1d0s0 is / c1t0d0s3 and c1t1d0s3 is /var c1t0d0s4 and c1t1d0s4 is /opt c1t0d0s6 and c1t1d0s6 is /usr/local So what about d1 and d7 ? d1 is swap and d7 is not mounted or used, which is a bit strange as we normaly use slice7 for the metadb, but on this server slice 5 is used for the metadb Code:
$ metadb
flags first blk block count
a m p luo 16 1034 /dev/dsk/c1t0d0s5
a p luo 1050 1034 /dev/dsk/c1t0d0s5

Thats the easy bit, the internal root disks, But how about those other metadevices ? The other metadevices are soft partitions made on logical drives from 5 3510 disk arrays and you need a few more commands to work out what is what. Code:
# sccli
sccli: selected device /dev/rdsk/c2t600C0FF000000000086A4C1A6991D300d0s2 [SUN StorEdge 3510 SN#086A4C]

Above you can see that we have 5 logical drives, ld0 -> ld4. Using all this output we get the following. Drive 4 is logical drive ld0 and is metadevice d90 (relavent sections are in bold) ld0 is 955GB and is a RAID5 of 8 physical disks metadevice d90 is split up into soft partitions d91 -> d96 You can see what d91 -> d96 is mounted as in the df -k output If you want to know what disks make up ld0 (d90) you will need to use sccli and run the command show disks. The output below has been edited, I didn't want to list all 75 disks. Code:

A long example, but hopefully covers what you might have on your end. Just for completeness of this example, this is how the root disk is partitioned.. Code:
Total disk cylinders available: 14087 + 2 (reserved cylinders) Part Tag Flag Cylinders Size Blocks 0 root wm 0 - 412 4.01GB (413/0/0) 8405376 1 swap wu 413 - 1237 8.01GB (825/0/0) 16790400 2 backup wm 0 - 14086 136.71GB (14087/0/0) 286698624 3 var wm 1238 - 2062 8.01GB (825/0/0) 16790400 4 unassigned wm 2063 - 2887 8.01GB (825/0/0) 16790400 5 unassigned wm 2888 - 2889 19.88MB (2/0/0) 40704 6 usr wm 2890 - 3714 8.01GB (825/0/0) 16790400 7 unassigned wm 3715 - 14086 100.66GB (10372/0/0) 211090944 I don't like the way its sliced up, but this server has been around here longer then I have been.
