VxVM not able to detect new LUN

[timus]

Configuration details -
OS - HP-UX B.11.23 U ia64
VxVM version 5.0

Problem description-

Added a new 70GB LUN from EMC CX-380 to the host.
diskinfo /dev/rdsk/c19t5d6
SCSI describe of /dev/rdsk/c19t5d6:
vendor: DGC
product id: CX3-80WDR5
type: direct access
size: 70709760 Kbytes
bytes per sector: 512

The new LUN is detected by OS, but VxVM is not able to detect it. i.e the LUN does not show in "vxdisk list" output.

Steps done so far -

1- ioscan -fnC disk
2- vxdctl enable / vxdisk scandisks
3- vxdisksetup -if c19t5d6
VxVM vxdisksetup ERROR V-5-2-43 c19t5d6: Invalid disk device for vxdisksetup

Please suggest any solution except "reboot"

Thanks

hi,
Initialize LUN to use with VxVM disk groups

#vxdisk scandisks

The above steps had already been tried but of no help

Incident E901010 - When a CLARiiON array is configured in A/PF mode, after introducing a new path, the vxdisk scandisks command might take more than an hour to complete.

Resolution: A fix for the issue is expected to be available when the 5.0 MP1RP2 patch is released

>> CONCLUSION -- install latests HP-UX 11.23 vxvm 5.0 patchset


Thus, install latest HP-UX 11.23 vxvm 5.0 patchset. (which can be found via the itrc patch database link (find HP-UX patches in a patch set ).. and yes the system will reboot as part of the patch(set) installation ...)

Greetz,

Hi timus,

though I only use VxVM under Solaris where the disk setup differs slightly (e.g. devfsadm -c disk, labeling via format) the steps you had performed under HP-UX look ok to me.

After the vxdctl enable (step 2)
is for instance a

# vxdisk -o alldgs list


listing the new disk (unassociated to any DG and marked "error" unless the vxdisksetup hasn't taken effect yet)?

As you can query the diskinfo its device file should also be in place.
Otherwise I would have suggested to run an inssf.

[Fidel Monreal]

I think you should have also done an insf -e. For the dsf's.

1. ioscan -f
2. insf -e
3. vxdctl enable
4. vxdisksetup -i
