I am using SPARC Solaris 11.1 with EFI labelled disks.
I am new to ZFS file systems and slightly stuck when trying to create a partition (slice) on one of my LUNs.
EFI labels use sectors and blocks and I am not sure how exactly it works.
From here I can try and create a partition but when I have to enter the Starting Sector, I get confused, as you can see from the below code.
I have tried to understand the sectors and so on, but cannot work out what sector I need to create from.
Any help would be greatly appreciated and/or info on sectors.
Each slice must not ovewrite other so start sector for a slice should be last sector of previous one + 1
I.g. in your table you can't create slice 1 because first sector should be 1007583
that is already in reserved slice 8
If you don't like how partition table is made, you should modify it (i.g. you should decrease slice 0), but in this case you loss data
Slice 8 is a reserved area at the end of the disk.
I don't see too much wrong with what you are doing except my first questions are:
1. What hardware is this?
2. What version of Solaris
3. The disk is being recognised as a 500MB disk. Emphasis on the "MB"! Is that right????
4. What type of disk is it? SCSI, SATA, IDE or what? Showing as a NetApp LUN?
If it is right, it's been a long time since I've seen one of those.

Oh, and one more question:
5. Have you actually written an EFI label to this disk?
(EFI labels occupy 34 sectors (0-33) so the first partition usually starts at sector 34.)
If you haven't written the EFI label you might need to use:
expert mode to do that.

I thought I had figured this out at one point, but I can't remember. Is there a way/command to get the UUIDs of a disk's partitions/slices in FreeBSD? Linux has the blkid command, which doesn't seem to be available. (2 Replies)

we have a ZFS file system that was created as a pool of just one disk (raid on a SAN) when this was created it was done as a whole disk, and so EFI label.
now we want to mount this file system into an LDOM.
my understanding of how ldom's and disk works this is that we can only do this as a... (1 Reply)
Hi Peeps,
Can anyone help me an EFI lablel on a 3510 raid array that I cannot get rid of, format -e and label just asks you if you want to label it. Want an SMI label writing to it.
Anyone got any ideas on how to remove the EFI label?
Thanks in advance
