EMC Symmetrix devices not available on second HBA
no error messages are apparent in syslog.
Both HBA's are set up the same.
Why are the new devices being seen on only 1 HBA? What to check for? reboot is not possible at this stage!

Try to use this command:
#symcfg discover
#powermt config
#powermt display
#powermt save

Re: EMC Symmetrix devices not available on second HBA
SYMCLI not installed on this host. Can already see the DMX as it picks up the existing disk devices on both HBA's and the new devices on 1x HBA.

Re: EMC Symmetrix devices not available on second HBA
You can try the following ,
# rmsf path ( The paths are showing NO_HW or not sensing).
# ioscan -fnc disk (check)
# insf -e
# symcfg discover
# powermt display ( check for any dead path)
# powermt check (checks and corrects dead path).
# powermt config
# powermt save
If doesnt solve pls letus know some more details.
Cheers,
RajD.

Re: EMC Symmetrix devices not available on second HBA
As previously stated PowerPath (powermt cmds) is not installed. server has been up for 122 days with existing devices from the DMX. It is only the newly allocated devices that are not being "seen" by one of the HBA's.
Firmware/software/patches etc remain the same/unchanged betweeen the two HBA's.

Re: EMC Symmetrix devices not available on second HBA
Have the new devices been presented out of each path from the EMC?

Re: EMC Symmetrix devices not available on second HBA
The devices configured for this server are provisioned through symcli commands and are presented to each FC HBA wwn. this was checked on the vcmdb database of the DMX. the devices were unmasked and unmapped then re mapped to directors and then remasked to the wwn of the HBA's this has been checked by EMC representative.

Re: EMC Symmetrix devices not available on second HBA
Re-masked devices back to firstHBA and server now sees all new devices on both HBA's.
