GPT disk for Windows

Windows supports the basic disk called GPT disk using GUID partition instead of the Signature.

The GPT disk also can be used as an S-VOL of the BC. Therefore, RAID Manager supports

saving/restoring the GUID DiskId of the GPT Basic disk to the inqraid command.

• gvinfex option (Windows 2003/2008 only)

This option retrieves the LUN signature and volume layout information by way of a raw device

file provided via STDIN or arguments, and saves it in a system disk file with the following

format:

\WindowsDirectory\VOLssss_llll.ini

where

ssss = serial#

llll = LDEV#

Normally, this option is used to save the Disk signature/ GUID DiskId and volume layout

information once, after it has been written on a potential (and before its paircreate). You do

not need to directly view these host files.

For example, saves the volume information for all physical drives:

D:\HORCM\etc>inqraid $Phys -gvinfex -CLI

\\.\PhysicalDrive10:

# Harddisk10 -> [VOL61459_448_DA7C0D91] [OPEN-V ]

\\.\PhysicalDrive11:

# Harddisk11 -> [VOL61459_449_D4CB5F17-2ADC-4FEE-8650-D3628379E8F5] [OPEN-V ]

\\.\PhysicalDrive12:

# Harddisk12 -> [VOL61459_450_9ABDCB73-3BA1-4048-9E94-22E3798C3B61] [OPEN-V ]

• -svinfex[=PTN] option (Windows 2003 only)

This option writes LUN signature/GUID DiskId and volume layout information (that had

previously been saved in a system disk file) by way of a raw device file provided via STDIN

or arguments.

This option gets the serial# and LDEV# of the RAID storage system for the target device using

SCSI Inquiry, and writes the signature/GUID DiskId and volume layout information from the

VOLssss_llll.ini file to the target device.

This option will work correctly (even if Harddisk# changes due to configuration changes)

because the signature/GUID DiskId and volume layout information is associated the array

serial# and LDEV# (not Harddisk#).

• [=PTN]

This option specifies a string pattern usable to select only the pertinent output lines being

provide from STDIN. If used as shown, only the pairdisplay output lines containing

Harddisk would be used to cause signature writing.

D:\HORCM\etc>pairdisplay -l -fd -g URA | inqraid -svinfex=Harddisk

[VOL61459_448_DA7C0D91] -> Harddisk10 [OPEN-V ]

[VOL61459_449_D4CB5F17-2ADC-4FEE-8650-D3628379E8F5] -> Harddisk11 [OPEN-V ]

[VOL61459_450_9ABDCB73-3BA1-4048-9E94-22E3798C3B61] -> Harddisk12 [OPEN-V ]

• -gplbaex option (Windows 2003 Only)

This option is used for displaying usable LBA on a Physical drive in units of 512 bytes, and

is used to specify [slba] [elba] options for raidvchkset command.

C:\HORCM\Tool>inqraid -CLI -gplbaex hd10,13

Harddisk10 : SLBA = 0x0000003f ELBA = 0x013fe5d9 PCNT = 1 [OPEN-V ]

Harddisk11 : SLBA = 0x00000022 ELBA = 0x013fffdf PCNT = 2 [OPEN-V ]

Harddisk12 : SLBA = 0x00000022 ELBA = 0x013fffdf PCNT = 3 [OPEN-V ]

SLBA: displays usable starting LBA in units of 512 bytes

ELBA: displays usable ending LBA (ELBA -1) in units of 512 bytes

PCNT: displays the number of partitions
