When installing an engineering hotfix (EHF) on a vCMP guest via block-device, sometimes it fails with 'reason unknown'. -- /var/log/liveinstall may contain an error similar to: I/O error : Input/output error /tmp/lind_util.voCQOs/BIGIP1610/install/fsinfo.xml:1: parser error : Document is empty -- /var/log/kern.log may contain an error similar to: Aug 14 14:15:54 bigip1 info kernel: attempt to access beyond end of device Aug 14 14:15:54 bigip1 info kernel: sr0: rw=0, want=3560560, limit=312712


Sometimes the EHF installation fails on the guest.


This might occur after multiple attempts to install an EHF on a vCMP guest via block-device: tmsh install sys software block-device-hotfix Hotfix-BIGIP- volume HD1.3


-- Retry the software installation. -- If the software installation continues to fail, copy the ISO images into the vCMP guest, and use those to perform the installation.
