3.2.3 Checking the HiRDB configuration at the main site

After you have finished setting up RAID Manager's environment and setting up the environment for the HiRDB system at the main site, execute the pdconfchk and pdrisechk commands to check the configuration of the HiRDB system at the main site.

Note that there are items that these commands cannot check. Therefore, the HiRDB administrator must manually check the items that cannot be checked by these commands. The following table lists the HiRDB configuration items, and indicates whether they can or cannot be checked by these commands.

Table 3-5 HiRDB configuration items and whether they can or cannot be checked by the commands

Item Check item Checked by the command?
pdconfchk pdrisechk
1 Whether the required operands are specified Y Y
2 Whether the RAID Manager configuration file is correctly specified N N
3 Whether the RAID Manager instance number is correct#1 N N
4 Whether the RAID Manager instance has started#2 N N
5 Whether all paired logical volume groups that require update copy are present N Y#3
6 For the volume attribute of the paired logical volume group in item 5, whether the site that executed the pdrisechk command is set to P-VOL N Y
7 For the pair status of the paired logical volume group in item 5, whether the site that executed the pdrisechk command is set to PAIR N Y
8 Whether the fence level of the paired logical volume group in item 5 satisfies the specification indicated in Table 3-2 Fence level to be specified when executing the paircreate command N Y
9 Of the paired logical volume groups in item 5, whether the asynchronous paired volume has correctly set up a consistency group according to the rules described in Table 3-3 Consistency group (value of the -f option) to be specified when executing the paircreate command) N N
10 Whether all HiRDB files are present Y#4 N
11 Whether the HiRDB files are located in the correct paired logical volume group according to the rules described in 2.5.3(1) Naming rules N N

Legend:
Y: Can be checked
N: Cannot be checked. Must be manually checked by the HiRDB administrator.

#1
If the instance number (HORCMINST) of the RAID Manager that you specify in HiRDB points to another existing instance, items 5 through 9 are not correctly checked.

#2
If the instance corresponding to the instance number (HORCMINST) of the RAID Manager that you specify in HiRDB is not active, items 5 through 9 are not correctly checked.

#3
If you are using a floating server (back-end server for fetching data) and the KFPS04680-E error message is output, indicating that there is no paired logical volume group that corresponds to the HiRDB file in which RDAREAs are located, ignore it.

#4
N (cannot be checked) if the -n option is specified.
