Re: One loop connection lost
However, this could be a hardware or firmware issue.
The disk has version HP05, but version HP09 is current!
Consider to pull the drive and push it back, update the firmware!
Hope this helps!
Regards
Torsten.

Re: One loop connection lost
Command View 9.3 - Likely that the XCS firmware is also old.

Re: One loop connection lost
If you have enough free space nothing bad will happen.
Any vdisk may belong to each disk within the diskgroup.
Hope this helps!

Torsten.

Re: One loop connection lost
Hi,
we have16 hpux serversand these servers are connected to storage.
we see the harddisk information on storage.
for example:---
Disk Bay Disk Drive General I/O
Identification Name: Disk 037 Loop: 1 Node WWN: 2000-001D-3819-6F5D UUID:
Physical Type: Online Formatted capacity: 136.73 GB Model number: BF146DA47C Serial number: 3QN0KQ5S Firmware version: HP05 Condition/State Operational state: One loop connection lost Data state: Not migrating Data progress: n/a Failure prediction: No Media accessible: Yes
System Requested usage: Grouped Actual usage: Grouped Disk group: Default Disk Group Occupancy: 92.74 GB
My quey is that
This harddisk belongs to which hpux server or assign?
if you have any command to see the storage harddisk serial no or model no. which run on HP-UX Machine ?
Anyway
Thanks a lot.
Thanks
aamir

Re: One loop connection lost
If you ungroup a disk, the system will copy all data from this disk to another disk until the disk is empty.
As said, no problem unless there is not enough free space within the diskgroup.
Hope this helps!

Torsten.

Re: One loop connection lost
There is storage virtualization in play. EVA is aggregating storage space of multiple drives in a disk group. This is done to scatter data across more physical spindles then normal RAID will allow. Resulting in better performance. EVA will decide which drive data should be written to.
Based on error you might want to upgrade firmware before anything else
Hope this helps
Cheers!!
