You have either to install efixes (generally generating as many problems as it is solving) or update to the latest level.
Current version for HACMP is 7.1.3 and 6.1 is already EOL by September. Do yourself a favour and use this maintenance window to update to the as latest version as possible. DO NOT use any version below 7.1.3 if updating to 7.1! Many things (like the repo disks via NPIV with non-IBM storage) worked only in theory, not in practice. 7.1.3 is more or less stable. I have some 40-50 clusters running here and could go on for pages and pages about the workarounds and quick-fixes we had to use to get working clusters with the earlier versions of 7.1.
You do not need to: as i said, create your LPARs when your old cluster is still working, from teh mksysbs (plus necessary updates, see above), create a NEW 7.1-cluster and test that until you are ready to make the move. You can pre-create the complete cluster-configuration into a series of commands now, because FINALLY the clmgr-command really works and it is possible to do a cluster-config via commandline! This (not having to navigate all these SMITTY-menus all the time) is by far the biggest relief since i work with HACMP.
You said you needed to use new IP-addresses anyway, so don't bother. Create your new cluster with the new addresses and test thoroughly, then make the transition basically by moving the data disks (they are NPIV, no?) to the new LPARs.
It might work, but again: you don't need that. I can give you a complete procedure for setting up a (7.1-)-cluster and in fact it is 10 minutes work now, only a few commands. Far better and far easier than to navigate these endless SMIT-menus.
I hope this helps.

/PS: don't get me wrong: SMITty is fine if you don't know exactly what you want to do and what format a certain command is. But for what i do daily and know exactly what and how to do SMITty is more a hindrance than a tool.
You're definitely a life saver! Updating to HA 7.1.3 makes sense. We have been using smitty which definitely take more than 10 mins lol.
If it's possible can you give me a complete procedure for setting up a (7.1-)-cluster that will help me a lot.

CONSTANTS
IEEE80211_HW_HAS_RATE_CONTROL
The hardware or firmware includes rate control, and cannot be controlled by the stack. As such, no rate control algorithm should be
instantiated, and the TX rate reported to userspace will be taken from the TX status instead of the rate control algorithm. Note that
this requires that the driver implement a number of callbacks so it has the correct information, it needs to have the set_rts_threshold
callback and must look at the BSS config use_cts_prot for G/N protection, use_short_slot for slot timing in 2.4 GHz and
use_short_preamble for preambles for CCK frames.
IEEE80211_HW_RX_INCLUDES_FCS
Indicates that received frames passed to the stack include the FCS at the end.
IEEE80211_HW_HOST_BROADCAST_PS_BUFFERING
Some wireless LAN chipsets buffer broadcast/multicast frames for power saving stations in the hardware/firmware and others rely on the
host system for such buffering. This option is used to configure the IEEE 802.11 upper layer to buffer broadcast and multicast frames
when there are power saving stations so that the driver can fetch them with ieee80211_get_buffered_bc.
IEEE80211_HW_2GHZ_SHORT_SLOT_INCAPABLE
Hardware is not capable of short slot operation on the 2.4 GHz band.
IEEE80211_HW_2GHZ_SHORT_PREAMBLE_INCAPABLE
Hardware is not capable of receiving frames with short preamble on the 2.4 GHz band.
IEEE80211_HW_SIGNAL_UNSPEC
Hardware can provide signal values but we don't know its units. We expect values between 0 and max_signal. If possible please provide
dB or dBm instead.
IEEE80211_HW_SIGNAL_DBM
Hardware gives signal values in dBm, decibel difference from one milliwatt. This is the preferred method since it is standardized
between different devices. max_signal does not need to be set.
IEEE80211_HW_NOISE_DBM
Hardware can provide noise (radio interference) values in units dBm, decibel difference from one milliwatt.
IEEE80211_HW_SPECTRUM_MGMT
Hardware supports spectrum management defined in 802.11h Measurement, Channel Switch, Quieting, TPC
IEEE80211_HW_AMPDU_AGGREGATION
Hardware supports 11n A-MPDU aggregation.
IEEE80211_HW_SUPPORTS_PS
Hardware has power save support (i.e. can go to sleep).
IEEE80211_HW_PS_NULLFUNC_STACK
Hardware requires nullfunc frame handling in stack, implies stack support for dynamic PS.
IEEE80211_HW_SUPPORTS_DYNAMIC_PS
Hardware has support for dynamic PS.
IEEE80211_HW_MFP_CAPABLE
Hardware supports management frame protection (MFP, IEEE 802.11w).
IEEE80211_HW_BEACON_FILTER
Hardware supports dropping of irrelevant beacon frames to avoid waking up cpu.
IEEE80211_HW_SUPPORTS_STATIC_SMPS
Hardware supports static spatial multiplexing powersave, ie. can turn off all but one chain even on HT connections that should be using
more chains.
IEEE80211_HW_SUPPORTS_DYNAMIC_SMPS
Hardware supports dynamic spatial multiplexing powersave, ie. can turn off all but one chain and then wake the rest up as required
after, for example, rts/cts handshake.
IEEE80211_HW_SUPPORTS_UAPSD
Hardware supports Unscheduled Automatic Power Save Delivery (U-APSD) in managed mode. The mode is configured with conf_tx operation.
IEEE80211_HW_REPORTS_TX_ACK_STATUS
Hardware can provide ack status reports of Tx frames to the stack.
DESCRIPTION
These flags are used to indicate hardware capabilities to the stack. Generally, flags here should have their meaning done in a way that the
simplest hardware doesn't need setting any particular flags. There are some exceptions to this rule, however, so you are advised to review
these flags carefully.
