Map Command at EFI

Hi All,

Please explain the below output:

=====================
Shell> map -r
Device mapping table
fs0 : Acpi(HWP0002,100)/Pci(1|0)/Scsi(Pun1,Lun0)/HD(Part1,Sig287AB95C-E9D7-11DE-8002-D6217B60E588) <<<<

fs1 : Acpi(HWP0002,100)/Pci(1|0)/Scsi(Pun1,Lun0)/HD(Part3,Sig287AB998-E9D7-11DE-8004-D6217B60E588) <<<<

blk0 : Acpi(HWP0002,0)/Pci(2|0)/Ata(Primary,Master)
blk1 : Acpi(HWP0002,100)/Pci(1|0)/Scsi(Pun0,Lun0)
blk2 : Acpi(HWP0002,100)/Pci(1|0)/Scsi(Pun1,Lun0)
blk3 : Acpi(HWP0002,100)/Pci(1|0)/Scsi(Pun1,Lun0)/HD(Part1,Sig287AB95C-E9D7-11DE-8002-D6217B60E588)
blk4 : Acpi(HWP0002,100)/Pci(1|0)/Scsi(Pun1,Lun0)/HD(Part2,Sig287AB97A-E9D7-11DE-8003-D6217B60E588)
blk5 : Acpi(HWP0002,100)/Pci(1|0)/Scsi(Pun1,Lun0)/HD(Part3,Sig287AB998-E9D7-11DE-8004-D6217B60E588)
blk6 : Acpi(HWP0002,100)/Pci(1|1)/Scsi(Pun2,Lun0)
====================

OS: 11.23
Model: rx2600
Boot Disk: One
Total Disks: Three

Please let me know following:
(Lot of questions though..)

1. How to find boot disk? (I know we can go into fsN: and see if fsN:\EFI\HPUX\HPUX.EFI is present or not). But is there any other way?

2. How to find which disk is local and which from san?

3. What is HD(Part1..) in fs0 and HD(Part3..) in fs1 ?

4. How can we make a guess for HW address of disks?


Thanks (for your patience going through all my queries)..!!

Re: Map Command at EFI

Hi

also once the system is booted, you can use the ioscan -e command to see the disks and device files in EFI notations

fs1:\> dir
Directory of: fs1:\

File Not Found
Exit status code: Not Found

That is correct but I was thinking about the situation when the system is down.
Still did not get any details of "part3" from "ioscan -fneC disk"

Re: Map Command at EFI

Q2: all listed disks shown in the map output above are local disks, no SAN disks seen here.

A SAN disk would be shown with his WWN i.e.

blk9 : Acpi(HPQ0002,PNP0A08,400)/Pci(0|0)/Pci(0|0)/Fibre(WWN50060E800588E261,Lun0)
blkA : Acpi(HPQ0002,PNP0A08,400)/Pci(0|0)/Pci(0|0)/Fibre(WWN50060E800588E261,Lun4000000000000000)
blkB : Acpi(HPQ0002,PNP0A08,400)/Pci(0|0)/Pci(0|0)/Fibre(WWN50060E800588E261,Lun4001000000000000)


Did you try to run the command 'reconnect -r' before the map -r output ?
This should then list your SAN LUNs also in the map output.

The SCSI disk represented by BLK6: Pun2 does not seem to have a partition on it either.

Not really, unless you enable a "deep" SAN scan directly in the BIOS of the FC card.

Hope this helps!

Re: Map Command at EFI

>>3. What is HD(Part1..) in fs0 and HD(Part3..) in fs1 ?

I am not sure if this is the answer you are looking for...

The designation Part1 and Part3 refer to FAT partitions that are needed on the boot disk. They are formatted with FAT32 filesystems (referred to by the fsN: designation).

Part1 is the EFI system partition where the boot loaders and other tools are typically found.

Part3 is known as HP Service Partition and is reserved for the Itanium version of ODE (offline diagnostics environment).

An easy way to view these partitions only is by using the 'map -fs' from the Shell> prompt.
