Several device files missing after ignite recovery

[ Edited ]

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:

 

/dev/beep

/dev/diag/diag2

/dev/echo

/dev/ptmx

/dev/rscsi

/dev/strlog

 

Have anyone experienced this ?

 

HP said this has not been reported / documented yet .

Re: Several device files missing after ignite recovery

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 (!)

 

(ISCSI:

 

Although , not the choice for your HA critical clusters, but our first choice for

 

test and development systems , because its low costs. )

 

Workaround:

 

1. Run insf -C pseudo  after the recovery

 

or

 

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:

 

1.

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.

 

2.

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.
