86 HP StorageWorks Disk Array XP RAID Manager: User’s Guide

• raidscan –find inst

RM recognizes permitted volumes as a result of executing raidscan

–find inst

(the Permission command). This command issues a SCSI

inquiry to the specified device file to get the array Ser# and volume

LDEV# from the XP array. Then, it cross checks volumes in the

horcm.conf file against host viewable volumes and stores the result

within the RM instance.

The following example shows the relationship between device files

and the

horcm.conf file upon manual execution of the Permission

command in an HP-UX environment. Operations to all volumes

displayed by

ioscan will be allowed.

Example

(HP-UX)

# 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

Permitting operations on protected volumes

Protection Mode requires a recognition step to check the host accessibility

of volumes against the

horcm.conf file at RM startup, using a command

device with protection ON. This registration process (

c or d) is executed

automatically by

/etc/horcmgr at RM startup.

c The following is executed to register permitted volumes in a file

($HORCMPERM). If the $HORCMPERM file already exists, then it will

use the existing file without doing a new

ioscan (d).

If you want to permit even fewer volumes, edit the device file list in the

$HORCMPERM file. If you try to add device files that

ioscan does not see

(due to nonexistence or a LUN security product), an error will be returned

at access time. This file is simply the text output (device files only) of a

prior

ioscan with the non XP device files removed.
