>Not even after an ioscan
But what ioscan are you talking about?
ioscan is not the same as ioscan -funCdisk (the first rescan all the hardware, not the second...)
So before looking forward, as suggested, reboot with your disk subsystem up, perhaps go single user then init 2 then do an ioscan, the ioscan -funC disk and see if you see your disks now. config files wont help if you dont succeed here
Next, are you in cluster?
In cluster the vg are in exclusive mode and so are not activated automatically, If you were and no more then update /etc/lvmrc file to automatically activate those VGs
All the best

diskinfo
diskinfo(1M) diskinfo(1M)
NAME
diskinfo - describe characteristics of a disk device
SYNOPSIS
character_devicefile
DESCRIPTION
The command determines whether the character special file named by character_devicefile is associated with a SCSI or floppy disk drive. If
so, summarizes the disk's characteristics.
The command displays information about the following characteristics of disk drives:
Vendor name Manufacturer of the drive (SCSI only)
Product ID Product identification number or ASCII name
Type Floppy or SCSI classification for the device
Disk Size of disk specified in bytes
Sector Specified as bytes per sector
Both the size of disk and bytes per sector represent formatted media.
Options
The command recognizes the following options:
Return the size of the disk in 1024-byte sectors.
Display a verbose summary of all of the information
available from the device. For floppy drives, this option has no effect.
SCSI disk devices return the following:
Vendor and product ID
Device type
Size (in bytes and in logical blocks)
Bytes per sector
Revision level
SCSI conformance level data
DIAGNOSTICS
Most of the diagnostic messages from are self-explanatory. However, one diagnostic message deserves further clarification. If the command
fails to access the lunpath corresponding to a given special file, it displays the following diagnostics data, which contains device iden-
tification and capability information:
device type 127 (unknown); device is inaccessible
iso ecma ansi rmb dtq resv rdf
WARNINGS
As of release 10.20 of HP-UX, certain IDE devices, CD-ROMs in particular, will respond to inquiries as if they were SCSI devices. There-
fore, the text "SCSI describe" in the output of the command does not definitively mean that the disk is in fact a SCSI drive (especially in
the case of CD-ROMs). Use to check which type of INTERFACE node, SCSI or IDE, the device's hardware path lies beneath, in order to defini-
tively determine a drive's interface.
DEPENDENCIES
General
The command supports floppy and HP SCSI disk devices.
SCSI Devices
The SCSI specification provides for a wide variety of device-dependent formats. For non-HP devices, may be unable to interpret all of the
data returned by the device. Refer to the drive operating manual accompanying the unit for more information.
