Veritas Netbackup 命令行下的磁带添加步骤
a.在添加磁带前的准备
请先对NBU管理下的带库进行以下必要的信息统计:
1.运行以下的命令确认您需要添加磁带的带库是哪一个,有TLD(X)多个字样,代表有多个带库(一般一个带库配一个机械手)。
# tpconfig -d |grep robot
Currently defined robotics are:
TLD(0) robotic path = /dev/ovpass0,
2. 可用槽位数量的统计,并记下多个空白的槽位号(Slot Number),
一个号对应一个磁带(在没有活动的备份作业下进行统计,保证正确性):
# vmcheckxxx -rt tld -rn 0

3.确定所添加磁带的类型,注意查看media type 对应部分是磁带方式,所添加的磁带也要一致(对应一个带库中只有同种类型的驱动器):
# available_media
media media robot robot robot side/ ret size status
ID type type # slot face level KBytes

3422L2 HCART3 TLD 0 259 - 1 22788992 ACTIVE
0019L3 HCART3 TLD 0 232 - 1 1317927456 FULL
# tpconfig -l 这个带库中只有同种类型的驱动器

drive - 0 pcd - DISABL - IBM.DDSGEN5.000 /dev/rmt0.1
b.在确认没有活动备份作业的情况下进行以下操作,必要时停nbu服务。如果确定备份空闲时间有一个小时,足够放磁带到带库中了。否则,需停nbu服务。
在机器现场把需要添加的磁带准备好,新磁带必须先正确地贴好标示(添加磁带的类型必须正确),按照带库厂商的要求放置添加到相应的cap 里面(进、出带窗口)。
1.进入robtest 模式,手工把 cap 里面(进、出带窗口)的磁带移动到之前记录下来的slot 里面(一个槽号对应一个磁带)。批量放置好磁带到cap 里面(进、出带窗口)后
进行以下操作:
假设你放了3盒磁带带在磁带cap窗口(从上到下放),准备要放到S29,S53,S123的槽位中。
# robtest (这里是在备份主机上输入此命令)

2.不管是添加磁带还是从带库中取磁带,对于NBU来说需要进行磁带数据库的更新操作。
添加磁带的话,还需要更新到临时池scratch pool里面。
#vmupdate -rt tld -rn 0

Volume configuration successfully updated.
问题:
如果运行 vmupdate -rt tld -rn 0 时提示有磁带不能添加,且提示新加的磁带(有提示在哪个槽位)与带库中有相同的barcode,这样就不能添加。
需要弹出磁带。再重新运行 vmupdate -rt tld -rn 0,直到添加完毕 。
robtest 模式下弹出磁带:
Enter tld commands (? returns help information)
m s29 p10 把在29号槽中的磁带弹出到第10号出窗口
Initiating MOVE_MEDIUM from address 1053 to 778
MOVE_MEDIUM complete
c.更新磁带到scratch pool。更新之前请再次运行available_media,查看新加磁带状况,
包括在哪个pool中(如果添加的磁带是以前带库中的旧带,运行vmupdate可能会直接更新到scratch pool ,这样,加磁带完毕;新磁带的则不会。)
。
1.利用vmpool获取scratch pool Numbers,这里是 4,记下。
# vmpool -listall -bx
pool index host user group description
---------------------------------------------------------------------------------------------
None 0 ANYHOST ANY NONE the None pool
NetBackup 1 ANYHOST root (0) NONE the NetBackup pool
DataStore 2 ANYHOST root (0) NONE the DataStore pool
CatalogBackup 3 ANYHOST root (0) NONE NetBackup Catalog Backup pool
scratch 4 ANYHOST ANY NONE ----
2.利用vmchange 更新到scratch pool (如果添加的磁带是以前带库中的旧带,运行vmupdate可能会直接更新到scratch pool ;新的则不会。)
(Associate this volume with a different pool)
vmchange [-h
| ]
-p -m
# vmchagne -p 4 -m 2326L3 (把2326L3磁带更新到scratch 号为4的scratch pool,多个磁带用UltraEdit编辑批量运行);
完毕,最后请再次运行available_media确认新加磁带即可用available磁带数量是否比以前增加,是否在scratch pool 。
