Solaris Box - Cannot get luns back

Paul Hawkins — Wed, 01 Sep 2004 02:56:26 GMT

I trying to getback some luns from a sun box running solaris. I cannot delete the scsi paths in Remote Control as it senses there is I/O down the path. The only way I have been able to get around this is to shut the host down. I've got a feeling this is somehow caused by Dynamic Multi-Pathing...Any ideas?

Hi,

some questions : what is the type of your HBAs, do you use a multipathing soft and which one, what is your array ?

how do you loose your lun ? what did happen?

Hi, The HBA's are JNI, the DNP is Veritas, the array is XP512....The luns are'nt lused but presented as single luns...

and what do you want to do. Dealloc lun from the sun box to give the lun to another server ?

if so, did you remove the lun form the vm config on the sun box ?

For HDS Environments (HP XP512/1024, HDS9960/9980 and Sun StorEdge).. the proper way to remove a LUN presented to a host is to:

1. unmount filesystems on top of the volume if any vxedit
2. remove the volume vxdisk/vxedit
3. remove the disk from VxVM control (vxdiskadm)
4. remove PATH(s) LUN Manager/RM or Command View/XP

HTH.
