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 ﬁleasthemainnodeinthestandbynodeexceptforip_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 pair

s 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 informat

ion 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,ormkconf.sh commands,

specify cat/home/nasroot/horc_devﬁle instead of ls/dev/sd*.

Table34Executingtheinqraidcommandusingthesudocommand

$ 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.
