-find inst. The -find inst option is used to register the device file name to all mirror
descriptors of the LDEV map table for CCI and permit the matching volumes on horcm.conf
in protection mode, and is started from /etc/horcmgr automatically. Therefore the user will
not normally need to use this option. This option issues Inquiry to device file from the result
of STDIN. And CCI gets Ser# and LDEV# from RAID storage system. Then, CCI compares
Inquiry result to content of horcm.conf, and the result is stored within HORCM of the
instance. At the same time CCI shows the result of this option about the relation. This option
will also be terminated to avoid wasteful scanning when the registration has been finished
with based on horcm.conf, because HORCM does not need the registration any more.
# ioscan -fun | grep rdsk | raidscan -find inst
DEVICE_FILE Group PairVol PORT TARG LUN M SERIAL LDEV
/dev/rdsk/c0t3d0 oradb oradev1 CL1-D 3 0 - 35013 17
/dev/rdsk/c0t3d0 oradb oradev1 CL1-D 3 0 0 35013 17
Note: When multiple device files share the same LDEV, the first device file is registered to
the LDEV map table.
-find verify [MU#]. This option shows relation between group on horcm.conf and Device_File
registered to the LDEV map tables from DEVICE_FILE of STDIN.
# ioscan -fun | grep rdsk | raidscan -find verify -fd
DEVICE_FILE Group PairVol Device_File M SERIAL LDEV
/dev/rdsk/c0t3d0 oradb oradev1 c0t3d0 0 35013 17
/dev/rdsk/c0t3d1 oradb oradev2 Unknowm 0 35013 18
/dev/rdsk/c0t3d2 - - - 0 35013 19
Note: It shows shared LDEV among multiple device files, if there is difference between
DEVICE_FILE and Device_File. The user can also use this option to the command device that
specified non-protection mode. It is used for the purpose to see the relation between
DEVICE_FILE and the group of Horcm.conf.
-f[d]. The -f[d] option shows the Device_File that was registered on the group of HORCM,
based on the LDEV (as defined in the local instance configuration definition file).
