Scope related to RAID Manager XP
• Relationships of failover and failback on RAID Manager XP and NAS Blade system
RAID Manager XP is not subject to failover and failback by the NAS Blade system. Prepare the same
configuration file as the main node in the standby node except for ip_address in the HORCM_MON
section. If a failure occurs in the NAS package while RAID Manager XP is operating and failover
occurs, start RAID Manager XP in the standby side and continue operating Continuous Access XP
Journal.
• Protect feature
When using Continuous Access XP Journal in the NAS Blade system, you create and resynchronize
pairs using RAID Manager XP while the NAS Blade system does not recognize the S-VOL. Therefore,
you cannot use RAID Manager XP's protection facility because this facility prohibits operations of
volume pairs the system does not recognize.
• Executing RAID Manager XP commands
To execute RAID Manager XP commands using the nasroot account for logging in to a NAS package
using SSH, use the sudo command as follows:
Table 32 Executing the pairdisplay cmd. in RAID Mgr. XP using the sudo cmd.
$ sudo pairdisplay -gg VG01
Table 33 Exec. pairdisplay cmd. using a shell script created with SSH Client (for
SSH proto. ver. 2)
$ ssh -2 [email protected] sudo pairdisplay -gg VG01
NOTE:
Create a shell script on the OS the system administrator uses. For more information about creating
shell scripts, see the appropriate documentation for that OS.
• Special file names given from standard input to the RAID Manager XP command
When giving special file names from standard input to the raidscan, inqraid, or mkconf.sh commands,
specify cat/home/nasroot/horc_devfile instead of ls/dev/sd*.
Table 34 Executing the inqraid command using the sudo command
$ cat /home/nasroot/horc_devfile | sudo inqraid -CLI
Table 35 Exec. the inqraid cmd. with shell script created in SSH client (for SSH
format ver.2)
$ ssh -2 [email protected] "cat /home/nasroot/horc_devfile | sudo
inqraid -CLI"
• Notes for scanning the NAS package's port by the raidscan command
Information on /dev/sda-sdi equivalent to the NAS system LU (NAS OS LU and dump LU) can be
displayed when scanning the NAS package's port using the raidscan command. You should not
define this information in HORCM_DEV in the configuration file because you cannot use the NAS
system LU (NAS OS LU and dump LU) as P-VOLs and S-VOLs.
