Re: vgextend error - too many links
Does that mean I can add only upto 7 alternate links to the VG & not all of the disks. Also can you please tell me what does optimize & nonoptimized mean.
Shall i add all the optimize disks or non optimize disks as the alternate links.
I am new to this - thanks

Re: vgextend error - too many links
You can see always optimized for Controller B, non-opt. for controller A.
This simply means EVA controller B "owns" the lun and has optimal access to the lun.
Of course you need to have pathes to controller A *AND* B.
I don't no anything about your hardware layout, so I cannot suggest details.
Hope this helps!
Regards
Torsten.

Re: vgextend error - too many links
To get access to the LUN you need 1 link only.
All other links are for redundancy if the first link fails.
Now the question is - how much redundancy do you have / do you want?
The FC HBA (or mezzanine in your Blade) has 2 ports hard-wired directly to at least 1 switch - how many switches do you have in the C7000 enclosure?
What EVA model? How many links (or cables) from EVA to the switch or switches?
Hope this helps!
Regards
Torsten.

Re: vgextend error - too many links
But there is a firmware version 6110.
Can you check this again?
And:
Please check and confirm if the vDISK presentation setting is "HP-UX" on the EVA - nothing else (not "default" or "windows" ...).
Hope this helps!
Regards
Torsten.

Re: vgextend error - too many links
fc 0 0/4/0/0/0/0 fcd CLAIMED INTERFACE HP 4Gb Dual Port PCIe Fibre Channel Mezzanine (FC Port 1)
/dev/fcd0
fc 1 0/4/0/0/0/1 fcd CLAIMED INTERFACE HP 4Gb Dual Port PCIe Fibre Channel Mezzanine (FC Port 2)
/dev/fcd1
this is the 2-port mezzanine card where the eva is connected.
fc 2 0/5/0/0/0/0 fcd CLAIMED INTERFACE HP 4Gb Dual Port PCIe Fibre Channel Mezzanine (FC Port 1)
/dev/fcd2
fc 3 0/5/0/0/0/1 fcd CLAIMED INTERFACE HP 4Gb Dual Port PCIe Fibre Channel Mezzanine (FC Port 2)
/dev/fcd3
This is an "empty" HBA.
From the first port of the HBA:
disk 5 0/4/0/0/0/0.12.0.0.0.0.1 sdisk CLAIMED DEVICE HP HSV210
/dev/dsk/c1t0d1 /dev/rdsk/c1t0d1
disk 7 0/4/0/0/0/0.12.1.0.0.0.1 sdisk CLAIMED DEVICE HP HSV210
/dev/dsk/c3t0d1 /dev/rdsk/c3t0d1
disk 11 0/4/0/0/0/0.12.2.0.0.0.1 sdisk CLAIMED DEVICE HP HSV210
/dev/dsk/c5t0d1 /dev/rdsk/c5t0d1
disk 1 0/4/0/0/0/0.12.3.0.0.0.1 sdisk CLAIMED DEVICE HP HSV210
/dev/dsk/c7t0d1 /dev/rdsk/c7t0d1
Hmm, the EVA 6000 has only 4 hosts ports, but you see *all* 4 over each HBA port - that indicates to me there is no zoning configured to the switches.
Ask your SAN support people to zone each HBA port and a single controller together.
Example:
zone1
HBA port1 + EVA ctrlA
zone2:
HBA port2 + EVA ctrlB
This will reduce the amount of device files.
Regarding this style of device files:
disk 4 0/4/0/0/0/0.12.0.255.0.0.1 sdisk CLAIMED DEVICE HP HSV210
/dev/dsk/c2t0d1 /dev/rdsk/c2t0d1
(notice the "255") - this let me thing the vdisk presentation mode is NOT "hpux".
I may be wrong, but better to double check this.
Hope this helps!
Regards
Torsten.
