Our banking customer asked to do a crash recovery test on an rx3600.
Using Ignite-UX for backup / recovery I was not able to log in via ssh.
Logging in via the console I relalized /dev/ptmx were missing.
It was not restored with recovery and insf did not create it.
No errors in "install log" .
Version C.7.15.254 seems to be okay, but with C.7.16.283 C.7.17.391
recovering HPUX 11.31 2011/09 or greater produces all the below device files mising:
Have anyone experienced this ?
HP said this has not been reported / documented yet .

Update from HP support at last.
Error reproduced by the lab.
All pseudo device files are missing after ignite recovery.
Seems to be a bug in later IGNITE versions , but it is more likely an 'insf' problem.
It happens on servers having the iSCSI-00 bundle installed (!)
Although , not the choice for your HA critical clusters, but our first choice for
test and development systems , because its low costs. )
1. Run insf -C pseudo after the recovery
2. Remove the iSCSI-00 bundle if you do not need it. (No ISCSI based storage)
Customer request waiting for the sw developers a new insf patch:
QXCR1001344501: insf -e doesn't create pseudo devices when iSCSI initiator installed
No ETA yet.
So this is a new issue again for a server with ISCSI stoage configured.
The existing ones:
When you recover your system with ISCSI storage , you will get
'Wrong device files' errors starting up the ISCSi daemon during boot.
You need to remove both /dev/iscsi and /dev/isw and reboot in order /sbin/init.d/iscsi
can recreate the right dsfs.
IGNITE recovery is not able to import the volume groups based on ISCSI, because, the initiator
is not started in that phase.
QXCR1001329058 ER: Support recovery of system using iSCSI for non-root volumes.
Customer request is still waiting for the sw developers.
